Message to all designers of electronic devices:
your device should not emit light without a good reason
if your device must emit light, it should be possible to turn that light off
if your device's light cannot be turned off, it should be dim red or orange, and NEVER blue or white
Signed, a person trying to sleep
#room i'm staying in rn has an electronic... thermostat? i think? i dont know what it is tbh#but instead of buttons it has a touch display made up of a matrix of blue-white LEDs that DOES NOT TURN OFF AND IS SO BRIGHT

Illuminating the Future: Exploring the Dot Matrix LED Display Technology
Introduction
In the world of digital innovation, LED technology has emerged as a game-changer, revolutionizing the way we visualize information. Among the various LED display solutions, the dot matrix LED display stands out as a versatile and efficient option. This blog delves into the intricacies of dot matrix LED displays, exploring their applications, working principles, and the role they play in our everyday lives.
What is a Dot Matrix LED Display?
A dot matrix LED display, also known as an LED dot matrix display or LED matrix panel, is an array of individual LEDs arranged in a grid pattern. Each LED within the matrix is capable of illuminating independently, allowing the display to generate various patterns, shapes, and characters. These displays are commonly available in monochrome (single-color) or multi-color configurations, providing visual flexibility for a wide range of applications.
Understanding the Working Principle
The operation of a dot matrix LED display is based on the principles of multiplexing. Multiplexing is a technique used to control multiple LEDs with fewer input/output pins. In a typical configuration, the LED matrix is divided into rows and columns. By sequentially turning on specific rows and columns at a rapid rate, different LEDs can be activated to form a desired pattern or text.
For example, to display the letter "A" on a 5x7 dot matrix LED display, the corresponding LEDs in the matrix would be activated according to the pattern for the letter "A," with each row being illuminated one after another in quick succession to give the illusion of a static image.
Applications of Dot Matrix LED Displays
The versatility of dot matrix LED displays makes them ideal for a wide range of applications. Some of the common uses include:
Information Displays: Dot matrix LED displays are commonly used in public places, transportation systems, and sporting events to provide real-time information, such as arrival and departure times, scores, and announcements.
Message Boards: LED dot matrix displays are popular for creating dynamic and eye-catching message boards in retail stores, banks, and other commercial establishments to showcase advertisements and promotional content.
Indoor and Outdoor Signage: Due to their high visibility and ability to display custom graphics and messages, LED dot matrix displays are widely used in indoor and outdoor signage for businesses and public spaces.
Clocks and Timers: LED matrix displays are frequently integrated into digital clocks, countdown timers, and stopwatches, providing a clear and legible time display.
Gaming and Entertainment: LED dot matrix displays are also utilized in gaming consoles and handheld gaming devices to render graphics and textual content.
Advantages of Dot Matrix LED Displays
Energy-Efficient: LED technology is renowned for its energy efficiency, making dot matrix LED displays an eco-friendly choice compared to traditional display technologies.
High Brightness: The individual LEDs in a dot matrix display produce high-intensity illumination, ensuring excellent visibility even in brightly lit environments.
Compact and Lightweight: The compact size and lightweight nature of dot matrix LED displays make them easy to integrate into various devices and structures.
Flexible Content: With the ability to display custom content, dot matrix LED displays allow for dynamic and engaging visual experiences.
Conclusion
The dot matrix LED display has become an indispensable technology in today's digital landscape. Its versatility, energy efficiency, and ability to display custom content make it a popular choice for a diverse range of applications, from public information displays to advertising and gaming. As LED technology continues to advance, we can look forward to even more innovative applications of dot matrix LED displays, shaping a brighter and more visually engaging future for us all.

I've mentioned a battle called The Battle for The Thanatos a few times in my TFP Gilded Future Au and I figured it was about time I revealed just what this crucial battle was about.
So, the first thing to note is that the battle took place on the anniversary of Earth's cyberforming and that the battle was a major risk the Autobot Resistance had to gamble on.
So, as the Autobot Resistance slowly dwindled in numbers, losing many of their bases to the Decepticon Empire, Nova (Jack), using intelligence gathered by Enigma (Raf), authorised an major assault on an experimental Decepticon warship with the intention of capturing it.
The warship in question was the Thanatos, which was under the command of Starscream. Nova's battleplan was simple, Thundercracker and Predaking would lead an aerial assault upon the warship, drawing the attention of the vessels Vehicon and Insecticon defenders.
While Thundercracker and Predaking kept Starscream's attention focused on them, two teams would sneak into the warship, on team, led by Wildshock (Miko), was to secure the reactor while the other team, led by Enigma, would secure the bridge.
Enigma's team, comprised of Teardown (Vince), Scattershot, Nosecone, Lightspeed, Strafe, Afterburner and a few other Autobot warriors would encounter resistance on the bridge. While Enigma and Teardown engaging Starscream in battle, the Technobots and the few other Autobots that were with team set to work clearing out the command crew.
Wildshock's team, comprised of the Wreckers, would encounter their own resistance in the form of their longtime rivals, Squadron X, who were eager for a rematch to decide who the better team was. It was a fight that ultimately ended in the Wrecker's favour after Wildshock electrocuted and ripped Macabre's head clean from his body, allowing the Wrecker's to secure the reactor.
Starscream would succeed in sending a distress call to the Nemesis, informing Megatron of the assault. Megatron would in turn lead the reinforcements himself in the hopes of wiping out what remained of the Autobots.
Nova, Flamewarp (Sierra) and Ultra Magnus, coordinating the assault from the current Autobot base, would enter the fight with what remained the Autobot Resistance's fighting force, arriving the same time Megatron did.
While Ultra Magnus and Nova engaged Megatron in battle and Flamewarp fought Skywarp, Starscream would rip out Enigma's voice box, crushing it within his hands. His actions would anger Teardown who, in a fit of protective rage, rammed his fist through Starscream's chest, ripping his spark out and crushing it in the process whilst the Seeker was busy monologuing, ending his threat and allowing the Autobots to secure the bridge.
Now, Megatron would toss Nova aside, and using incorrect intel, assumed Ultra Magnus was the current Autobot leader, killed him by ripping his head clean from his body and proclaiming the Autobots leaderless. Nova would proceed to engage Megatron alone, the two of them fighting in a brutal and gruelling duel, a fight that both Autobot and Decepticon paused their own battle to watch.
Their fight tended when Nova was forced to pull back briefly, leading to Megatron to remark that Nova was not Optimus Prime, Nova however revealed that beating Megatron here was not his goal and instead said that reclaiming the Matrix was.
Reclaim the Matrix, Nova did, for as he told Megatron his intentions, he revealed the Matrix to be in his hands, having ripped it from the chain around Megatron's neck where he had proudly displayed it during the fight.
You can image that Megatron wasn't exaclty happy about this, and as Nova move to put the Matrix in his chest, Megatron charged him. Flamewarp would race forward in an attempt to give Nova time to put the Matrix in his chest, only for Megatron to toss her aside and fire several shots from his fusion cannon at Nova, shots which did nothing but twist away from Matrix.
Seeing that his fusion cannon was doing nothing, Megatron instead decided to use his sword and his hands to instead rip Nova apart, though by the time he'd closed the distance between the two, Nova had put the Matrix in his chest and transformed into Novalis Prime.
Now Novalise Prime, he proceeded to deliver a very one-sided beatdown on Megatron, finishing his chain of attacks off by firing several powerful shots into the Decepticon Leader's chest, dealing near fatal injuries to Megatron, which left Skywarp, the highest ranked Decepticon officer present in charge, the seeker making the wise decision to call for a full retreat.
The battle ended with the Autobots capturing the Thanatos, Nova becoming Novalis Prime and the Autobot Resistance reforming into The Last Autobots, though this battle would also lead to Megatron eventually becoming Galvatron and creating a new elite super soldier.

Card shuffle / Episode 3
Author: Akira
Characters: Hiiro, Niki, HiMERU, Kohaku
"So we're the stepping stones, the sacrificial lambs."
← Previous ✧ Directory ✧ Next →
[ Read on my site for a better viewing experience using Ois~su ♪ ]
Season: Winter
Location: Café Cinnamon
At the same time, in the ES building, at the coffee shop Cinnamon.
Hiiro: Hello! I'm Hiiro Amagi and I'll be taking over as the leader of Crazy:B starting today!
Everyone, I'm looking forward to working with you!
Niki: Aah, Otouto-san, come in, come in~♪
Please grab a seat there and sit tight for a sec, I'll treat you to lunch as a welcome~♪
HiMERU: —Shiina seems strangely upbeat.
Kohaku: Even if it's just for now, I reckon he's glad to be freed from Rinne-han's tyranny.
HiMERU: That sentiment is understandable. However, considering the plan ES has proposed, it's hard to be entirely happy about it.
A showdown between Crazy:B and ALKALOID, an all-out war...
There's certainly some demand for a clash between the newcomers who gained most prominence in ES's inaugural year.
However, there are several concerns.
First of all, given the grandiose and flashy nature of this project, there's a risk that the public perception of us may be fixed to "that" in the future.
Kohaku: We might be endlessly stuck playin' the roles of the Crazy:B and ALKALOID who're always at each other's throats...
I ain't fond of that at all, it might make it hard to get involved with my buddy Rabu-han.
HiMERU: Right. And structurally, there's a high probability that Crazy:B are set to be the villains, the losers in this plan.
That's how wrestling works. The heroes triumph over the villains and bask in the applause.
Kohaku: So we're the stepping stones, the sacrificial lambs. If someone had to pick between ALKALOID and Crazy:B as the villains... Right?
I'm sure that as the project organizers, ES'd prefer to promote the so very well-behaved ALKALOID.
HiMERU: Yes. However, it would be unpleasant to be used as a mere stepping stone in such a way.
While we may not be saints, HiMERU refuses to be demonized as a villain just to further emphasize the righteous.
Kohaku: ...Well, yeah, I ain't fond of that either. I don't mean to be cold-hearted, but we've got no obligation to prop ALKALOID up like that.
I'd be willin' to be a stepping stone for someone I like, but bein' forced to do so for folks I've got nothin' to do with is a different story.
HiMERU: Indeed. Therefore, HiMERU has devised a plan.
In accordance with this project's script, the leaders of Crazy:B and ALKALOID will be temporarily swapped, correct?
Our leader will no longer be that embodiment of evil, Rinne Amagi, but his younger brother, who is clearly a good kid at a glance.
Kohaku: Uh-huuh, I've got it, HiMERU-han. A leader's like a banner, and if that banner's been swapped out for a more innocent-lookin' one—
HiMERU: Exactly. Our overall image could also be painted in a positive light. No, let's make it so.
Under a new leader, we will be born again as virtuous beings. At least, we'll make it look that way to the world.
Then, we'll become the allies of justice, using the "villainous ALKALOID" led by Amagi as our own stepping stones.
We will no longer be the miserable losers, but the shining protagonists.
Kohaku: That's an enticin' idea. Yeah, if that's the case, what we need—
Hiiro: ...? Um, is it okay if I say hello?
Kohaku: Of course ♪ C'mere, c'mere, Hiiro-han!
Hehe. Things got a bit weird, but let's all get along, yeah? ♪
HiMERU: Yes ♪ Oops, the chair's a bit dusty. Let HiMERU take care of it with his handkerchief—Wipe, wipe ♪
Kohaku: (...A tad too obvious, ain't it?)
HiMERU: (No, Amagi's younger brother seems to be a very straightforward person.)
(Those kinds tend to be somewhat obtuse, so it's best to be overly blatant in displays of goodwill.)
Kohaku: (Ah, so by playin' nice llike this, Hiiro-han'll get motivated. And he might even be determined to do his best for us in Matrix.)
HiMERU: (Exactly. And so, by brilliantly defeating the ALKALOID led by Amagi, who seems blatantly unwilling to do so—we, Crazy:B, will emerge victorious in this project.)
HiMERU: (The victors are justice! Thus, we will become not miserable losers, but the winners who garner applause!)
Kohaku: (Feels a bit uncomfortable deceivin' such a genuinely good kid. But this is a real competition—ain't nothin' sinister 'bout it, so no one can call it cowardly~ Koh koh koh ♪)

What if ...
... your Tav was blind. At least, partially. This came from an idea on Twitter some time ago, and it's taken me long enough to polish up because I've fallen heavily into this idea. To the point of having come up with a whole backstory, including assistive magics that help them navigate the world, and ultimately having rolled them up as a character in BG3. I've got notes on how certain other scenes would play out, so there may be more to this in the future. For now, have their take on how to read Astarion's scars. (Dialogue is lifted directly from the game.)
You stood from your seat on the log by the fire, linking your fingers together and stretching your arms out in front of you. With a roll of your shoulders you peered carefully around. The night seemed dull, the shadows were blurrier, so you decided to err on the side of caution, and waved your hand in the motion to cast your Weave mapping. You waited a moment or two for the faint purple matrix to settle over the contours of the campsite, before moving to take your usual evening walk.
As you neared Astarion’s tent, you noticed him fidgeting, and could hear him muttering to himself, something about some letters. As you got closer, you could make out his arm twisted behind his back.
“What damned language is this?” he muttered, his fingers splayed out over his scars.
You paused, knowing he probably wasn’t expecting an answer, but you gave one anyway. “I thought you didn’t care what Cazador wrote on your back.”
He flinched, spinning around to face you. “Ah! There you are. I admit, I got curious.”
“Ah. Well, sorry to bother you. I’ll leave you alone.” you apologised and turned to go.
“Wait - I’m sorry. You caught me by surprise, that’s all. I’ve been tracing the scars on my back with my fingers, trying to read them by touch, but I can’t. They may as well be written in Rashemi.”
He was trying to read by touch? This gave you an idea. “Would you mind if I tried something?”
“I - this isn’t your problem, you know.”
“I know. But, I may be able to help read it, if you turn around”
He slowly turned away from you, displaying his back with the raised scars. You stepped closer to him, raising your hand to reach for his back, but paused, and nervously pulled your hand back. It hadn’t escaped your notice that when you’d spent the night with him, he had gently redirected your hands away from his back. You hadn’t known why at the time, but once you learned about his scars, it became clear. He’d wanted to avoid you touching them.
“And? What does it say?” he asked impatiently.
“I’m not sure yet.”
“But you can read it?”
“I can. But …”
“But? But what?” His voice was getting whiny in frustration.
“I need your consent for what I’m about to do.”
“What? Why?” He twisted to look over his shoulder at you, and you could make out a frown creasing his face.
“I’m mostly blind, remember. I have some sight, a little more than I used to, thanks to the parasite, but I can’t read normal books anymore. So I learned to read special books with raised letters. I learned to read by touch. Which is why I need your consent. I’d need to touch you. To touch your scars.”
“You read … by touch …” he whispered, turning away from you again, and you wished you could make out the look on his face. A heartbeat passed as he considered your offer. Two. Three.
“I - I suppose it couldn’t hurt.” You heard him sigh. “Go ahead. Please.”
You lifted your hands to his shoulders and cautiously placed your palms against his skin. He shivered a little, the warmth of your hands in stark contrast to his coolness. You ran your hands down to the first marks, and then around, using your palms to trace the outline of the design, to learn the placement of the marks. You felt him tense beneath your touch, fighting with himself not to pull away from you. You would swear he almost lost that battle as your fingers trailed down a line that led almost to his hips. As you began to trace the runes with your fingertips, you recognised the language.
“It’s Infernal” you gasped softly, pulling your hands back reflexively, your claws catching on the raised marks, and scratching lightly against his skin.
“Ah! What the hells are you - wait, did you say Infernal?”
“What language were you expecting?”
“I don’t know. Not that.”
You dropped your hands to your sides, and frowned. “Well, now you know. You will probably want to have Karlach read it for you.“
“But you can read it? You can tell me what it says?”
“I can. But I felt the tension in your back. I don’t want to make you any more uncomfortable than you already are with how I read.”
His voice was soft when he next spoke. “It’s … unusual, I’ll admit. But I trust you. I want you to read it for me.” He snorted. “Besides, Karlach would most likely tell me it’s a filthy limerick or some such.”
You smiled, a small huff of laughter escaping you. “Alright then. Just … bear with me a moment.”
You carefully traced each rune, your fingertips gliding from one to the next, following the circular patterns. Your lips moved soundlessly, as your mind translated the shapes into words. You frowned, running your fingers over it again, to be sure you had it right. You signed in annoyance.
“Well? Have you puzzled it out?” he asked softly. Despite that, you could hear the touch of impatience in his tone.
You sighed. “It’s not a poem, that’s for sure. A pact, maybe? It talks about ‘the fires below’, there’s mention of some kind of oath, and beyond that, it’s just fragments. Whatever this is, this is only a part of it.”
You let your hands fall away from his back, and you twined your fingers together as he turned back towards you.
“An infernal pact?” he pondered, his tone thoughtful. “But not even the whole text? What was that bastard up to?”
“You really have no idea what this is?”
“None at all … But if this is part of a contract, it must be powerful. Or valuable. Or both. No wonder he wants me back. What have I run off with …”
“If this is part of a contract, where’s the rest?”
“I wasn’t his only spawn. And he tortured us all - I imagine each of us are carrying a piece of this infernal contract. But what could a devil have offered Cazador? He had wealth, power, control - what more could you want?”
You didn’t miss the way he spat the words out - wealth, power, control. His desire, his jealousy was clear.
“Disappointed?”
Astarion shook his head. “Perplexed. This was a surprise, and Cazador’s surprises are never good. Then again, even he couldn’t know I’d be kidnapped. Whatever he planned, it’s gone wrong. Which gives us an advantage.”
Us. You winced at his use of the word, certain he didn’t mean to include you in whatever scheme he was planning. You knew full well that you were no one’s first choice for help. Not anymore
“We should tell the others, They might be able to help”
“No! No, let’s keep this between ourselves. At least until we know what it means.”
“Alright.” you agreed. Keeping his secrets was something you could certainly do. After all, it felt like you were doing that for almost everyone in camp. You turned to leave, but paused as he spoke up once more.
“Thank you, by the way. This is … well, it’s something.”
You turned your head to throw a smile back over your shoulder at him. “Don’t mention it.”
“Given the subject matter, I probably won’t.”

Why don't car manufacturers use polarized glass for their windscreens and their headlights? One 90° turned relative to the other. Wouldn't that avoid getting blinded by the headlights of cars coming from the opposite direction?
The idea of using polarized windshields and headlights to reduce glare is intriguing, but several technical, practical, and safety challenges make it unfeasible for widespread automotive use. Here's a breakdown of why this concept hasn't been adopted:
1. Polarization Mechanics & Limitations • Theory: If headlights emit vertically polarized light and windshields are horizontally polarized, the windshield would block glare from oncoming vehicles.
• Reality:
• Light Scattering: Headlights need to illuminate the road, which relies on light scattering. Polarized light scatters less effectively, reducing visibility of road surfaces, signs, and obstacles.
• Angular Sensitivity: Polarization effectiveness depends on alignment. On curved roads or hills, the 90° alignment between cars breaks down, causing glare to "leak" through.
2. Compromised Visibility for Drivers • Non-Polarized Light Sources: Traffic signals, brake lights, and streetlights emit unpolarized light. A polarized windshield would block critical light from these sources.
• Passenger Discomfort: Polarized windshields could distort or dim screens (e.g., GPS, infotainment) and heads-up displays (HUDs), which often rely on specific light orientations.
3. Technical Challenges • Durability: Polarized films degrade over time due to UV exposure, temperature swings, and physical wear, requiring frequent replacement.
• Manufacturing Complexity: Aligning polarization angles across millions of vehicles (and replacement parts) would demand precision incompatible with mass production.
• Cost: Polarizing all glass surfaces (windshields, headlights, mirrors) would significantly increase vehicle prices.
4. Safety and Regulatory Hurdles • Global Standards: Automotive regulations (e.g., FMVSS, ECE) require headlights to meet strict brightness and beam patterns. Polarization could reduce effective light output, violating these rules.
• Driver Adaptation: Tilting one’s head (e.g., to check mirrors) would alter the polarization angle, causing sudden glare or darkness.
5. Existing Alternatives Car manufacturers prioritize more practical solutions to reduce glare: • Automatic High-Beam Dimming: Uses cameras to detect oncoming traffic and adjust beams.
• Adaptive Driving Beams (ADB): Matrix LEDs or laser lights that "mask" oncoming cars while keeping other areas bright.
• Improved Optics: Better reflector designs and LED cutoff shields to minimize scatter.
• Anti-Glare Coatings: Hydrophobic or anti-reflective windshield coatings (e.g., BMW’s "Glareshield").
Historical Context • 1950s Experiments: Chrysler briefly tested polarized headlights and windshields in the 1950s but abandoned the concept due to the issues above.
• Sunglasses vs. Windshields: While polarized sunglasses work for individuals, scaling this to vehicles requires universal adoption—a near-impossible coordination challenge.
Conclusion While polarized glass could theoretically reduce glare, its trade-offs in safety, cost, and practicality make it inferior to modern adaptive lighting and optical innovations. Automotive engineers continue to focus on smart, dynamic systems (e.g., ADB, LiDAR-guided beams) that balance glare reduction with reliable visibility. Until polarization technology evolves to address these flaws, it’s unlikely to appear in production vehicles.

Warehouse Buzzer System
How Electronic Message Boards Assist In Updating

Electronic message boards are fairly prevalent today, and their usage seems to be proliferating. Message boards in electronic kind properly interact swiftly upgraded company memoranda, final timetable modifications, and marketing, three fairly various applications providing one an idea of the breadth that this medium has gotten to. Herein we explore the phenomenon both generally and in regards to the power released when incorporated with an integrated clock system.
Electronic message boards derive from a lengthy background of open-air communication making use of indicators, billboards, marquees, and so on. Trick attributes were the layouts utilized and the feedback time for updating info. The most usual style entailed drawing on comprehensive personality collections, containing letters, numbers, and spelling, to create words, hanging them from hooks or resting them on wooden slats.
Posts were changed by hand, and updates were thus irregular. In time, updating was improved and somewhat automated using electronic control, such as seen with old baseball park scoreboards.
However, there was still the danger of lacking specific characters and being rendered unable to display all words in your message. This problem was addressed when the dot matrix selection was created, which stood for any type of character (in any type of typeface)-- also graphics-- with a rectangular pattern of on-or-off dots. These could be published on paper, yet a lot more effective was to present them in grids of light bulbs or on a screen.
Mapping formulas converted text into ranges of dots virtually instantaneously, and while drivers entered on a console, messages scrolled across the screen in essentially live. This system still required manual work, however the display screen tool was much easier to read, new, and updatable in a matter of moments. Whence the birth of electronic message boards that utilized light bulbs as the dots, or pixels.
Early light bulbs were incandescent, and were really the only choice; nonetheless, they had brief life-spans and prone to failing from shock. By the millenium, light producing diodes (LED) were a fully grown innovation and available in several shades, including white. Additionally, they outlived incandescent light bulbs by approximately 50 times, were not so breakable, and rapidly came to be the recommended part for message boards.
In time developers got extra creative with the tool and wanted to have more than one "on" shade to deal with. LEDs can fulfill this desire with their 3-in-1 mix of the 3 primary colors to synthesize white light; by choosing different sub-combinations you can obtain 7 various shades.
At some point, upgrading had to transition out of its humble manual origins. Now, textual info can be gotten in real time or gotten from data sources, and software is utilized to map the information right into matrices of (color-coded) dots that get buffered and presented quickly, effortlessly, and effortlessly. Graphics can be incorporated if they are mapped in advance.
Therefore, the modern digital boards are essentially automated, though there are provisions for bypassing scheduled programs with brand-new content in emergencies. Synchronous timekeeping systems manage everything.
An intriguing advancement is the integration of sound signals with the visual information being displayed on a sign in either textual or visual kind. It is popular that a close coordination of both kinds of sensuous stimulations has a tendency to get the message throughout many successfully. It's not a combination of both elements into tune, yet rather the use of sounds (bells, tones, whistles) as focus grabbers to change emphasis of the target market to what the board is showing, whether it be information or other timely information. synchronized clocks for hospitals
The world has actually expanded tired with fixed messaging in regards to both web content and style. Things need to be vibrant to sign up, and this needs constant educational updates. With this article we have seen exactly how electronic message boards promote updating.

PoCoBot (2007) by the Business Design Laboratory, Nagoya, Japan. The Business Design Laboratory envisioned a fusion of the Personal Computer with robotics, and so the humanoid PoCoBot was born. PoCoBot is just like a regular PC but with arms and legs, an LED matrix for a face, and a built-in display and webcam. It comes with robot control software, "PoCoBoTWORKS", providing conversational communication, and interaction with peripheral devices like the optional servo-actuated arms.

Triple Matrix Bonnet Makes Big Bright Displays 🔴🟢🔵✨
With our latest work on getting HUB75 RGB matrices working on the Raspberry Pi 5
we can now create stunning LED displays. But what if we want more pixels? At some point, we max out the bandwidth of the RP1 chip, but we can still squeeze out additional performance by updating the PIO commands to output two or three matrix strings instead of just one.
Thus, the Triple Output RGB Matrix Bonnet you see here! We're using the classic Active-3 pinout
with a switch to select whether the 4th or 8th pin is connected to address E.
Since we expect large matrix grids drawing 10A+ of current, there's no onboard power management—the 5V supply should be connected separately through thick power wires. This board is for data only. If you aren't using port 3, the I2C remains available, so we've added a Stemma QT port for extra flexibility.
