Coming soon - This ESP32-C6 feather is a Matter of fact

ESP32-C6 (https://www.adafruit.com/product/5672) is Espressif’s first Wi-Fi 6 SoC integrating 2.4 GHz Wi-Fi 6, Bluetooth 5 (LE) and the 802.15.4 protocol. It brings the goodness you know from the low-cost C3 series (https://www.adafruit.com/product/5337) and improves it with Zigbee/802.15.4 at 2.4Ghz. That means it could make for great Matter (https://csa-iot.org/all-solutions/matter/) development hardware!

We took our Feather ESP32-S2 (https://www.adafruit.com/product/5000) and swapped out the 'S2 for a C6. Plus some re-routing and here's what we've got: a C6 Feather with lots of GPIO, lipoly charging and monitoring with the MAX17048, (https://www.adafruit.com/product/5580) NeoPixel, I2C Stemma QT port, and a second low-quiescent LDO for disabling the I2C and NeoPixel when we want ultra-low power usage. We also tossed a BME280 (https://www.adafruit.com/product/2652) on there, so you could use it immediately as a low power temp/hum/pressure sensor.

WARNING: LONG ASK INCOMING

For hobby electronics there’s two major kinds of processors: Microcomputers and Microcontrollers. Microcomputers are small full computer systems like the Raspberry Pi, they typically run a general-purpose OS (typically some flavor of Linux) and are useful for the kinds of projects that require basically a full computer to function, but not necessarily individual sensors. They’re a great place to start for people who don’t know a whole ton about programming or working with individual components because they typically can output a true GUI to a screen and have the capabilities of a regular desktop computer. They have a main processor, true RAM, and either large on-board storage space or a way to read a storage device, like an SD card.

Microcontrollers are less complicated (component wise) than microcomputers, but as a result are more difficult for total beginners to begin working with. They’re typically primarily a SoC (System on a Chip) processor without discrete RAM modules and a very small EEPROM (on-ship storage space) and need to have components wired and configured to them to be able to do much more than being a fancy calculator. They’re used for when you need something to carry out electronic functions or get sensor readings, but not necessarily a full operating system, so they’re best suited for small/integrated applications. Your helmet uses a microcontroller to control the LEDs you used in the Cunt Machine post.

I build high-power model rockets as a hobby and with my university team, so I work with both kinds of processor as part of designing payload systems. I typically prefer microcontrollers in these as most of what we do doesn’t need an actual OS to run, and they’re smaller/lighter than microcomputers. One of the advantages of a microcontroller is that it runs a Real-Time OS (RTOS) which forgoes all the user-friendliness of things like windows and linux to instead be the bare minimum backend necessary to run code uploaded into the processor. 

The main advantage of using a microcontroller is really that they’re typically a lot cheaper than microcomputers are and are plenty powerful for really embedded applications. They also make other parts of whatever system is being built cheaper/easier to integrate because they require less overhead to function - the raspberry pi needs a minimum of 5 volts of power to work, while a chip like an ESP32-PICO can run at 1.8V. 

The main way you make sensors/buttons/peripherals work with a microcontroller is via digital communication busses. There’s a few protocols, the most common being I2C, SPI, and UART. I’ll talk about I2C since that’s generally the most common. With I2C each component is assigned a 2-byte “address” that they’re identified by. When the controller sends a request signal on the I2C data bus, every sensor along the line will return their own signal, marked with their address so that they can be identified. It allows for a large number of devices to be put on the same lines and you can daisy-chain them through each other to the microcontroller.

I’ll be honest I really can’t think of a good way to say much more on the subject as like a starting message because I’ve been working with computers so long all the tech stuff for me is second nature, but if you have any questions ask away I can probably answer them or google them.

We're vibin' with Claude 3.7 and writing uBlox drivers 😎🤖🛰️

Heeeey, we're just having a super chill vibe here at the desk of Ladyada—writing a driver for the uBlox M8Q

https://blog.adafruit.com/2024/09/10/a-mini-gps-from-ublox-with-i2c-and-uart

, which has both I2C and UART interfaces. As expected, it can do everyday NMEA output, but it can also do UBX, a "compressed" protocol for advanced data reads and writes over I2C/UART—or even SPI on some other chips.

However, the UBX protocol is a hugely complex driver to implement, with dozens of commands and hundreds of flags. But why stress when you can viiiibe? We're using this beast of a spec as an excuse to try out the new Claude 3.7, which is doing great at chomping through the UBX documentation roughage and giving us some nice code on the other side. Within an hour, we're able to connect and switch to UBX mode by sending a well-formed message and receiving an ACK.

What we like about coding with a good LLM is that it does the work we sometimes get lazy over, like handling various error conditions, timeouts, and verbose error messages.

5 Common Mistakes in Battery Management Systems

There are a few common issues related to the time of adoption and usage of BMS that may affect longevity, safety, and efficiency of a battery pack. Here are five typical errors to avoid:

1. Inadequate Thermal Management

Mistake: Failing to adequately check and regulate the battery cells' temperature.

Consequence: Overheating brought on by poor thermal management might result in thermal runaway, lower battery efficiency, or a noticeably shorter battery life.

Solution: Make sure the Battery Management Systems (BMS) has several sensors for complete temperature monitoring, and when needed, combine it with an active heating or cooling system.

2. Ignoring Cell Balancing

Mistake: Not implementing cell balance in the battery pack or configuring it incorrectly.

Consequence: Ineffective cell balancing can cause individual cells to overcharge or undercharge, which can diminish the battery's total capacity and cause uneven wear and possibly damage to individual cells.

Solution: To ensure consistent charge levels in every cell, use a BMS with either passive or active cell balancing.

3. Overlooking BMS Compatibility

Mistake: Using a BMS that isn't entirely compatible with the battery chemistry or the battery pack's particular setup.

Consequence: Incompatibility can result in improper voltage limits, inappropriate protection, and even unsafe operating conditions.

Solution: Make the BMS specifically designed for the type of battery chemistry used (Lead Acid, Lithium-ion, etc.) and the type of battery pack layout series/parallel arrangement.

4. Inadequate Fault Detection and Diagnostics

Mistake: Not providing enough fault detection and diagnostic tools for the BMS.

Consequence: Faults like short circuits, cell failures, or wiring faults could go unreported without adequate fault detection, resulting in battery damage or dangerous situations.

Solution: Select a BMS (Battery Management Systems) that has advanced diagnostic and fault detection, data logging, real-time warning capability, and communications of problems with other systems or operators

5. Underestimating the Importance of Communication Protocols

Mistake: Integrating a BMS (Battery Management Systems) with other system components without using the proper communication standards.

Consequence: Inaccurate battery status reporting and other inefficiencies can result from poor communication, as might a complete system failure if vital information is not accurately exchanged with controllers or displays.

Solution: The BMS should be able to converse with and connect to the rest of the system: other vehicle control units, chargers, and user interfaces using the necessary protocols: CAN bus, I2C, etc.

Staying away from these common mistakes while selecting and setting a BMS enables you to ensure that your battery pack can serve for as long a time as possible safely and efficiently.

Lithion Power is a manufacturer of high-end Battery Management Systems that can realize maximum performance from any given battery while ensuring safety. BMS developed for electric vehicle applications, energy storage, and portable electronics are highly critical-they offer monitoring and protection with precision to extend the life of the battery and enhance its reliability.

Connectors: Facilitate electrical connections between the PCB and other refrigerator components to ensure seamless integration.

Working Principle PCB Main Assembly

The PCB Main Assembly operates on a set of programmed instructions that determine its behavior depending on sensor input and user command. The micro controller continuously monitors sensor input such as the reading of the temperature from the refrigerator compartment, and freezer. The microcontroller controls the transition of the compressor on, or off or the speed of the fan and also the defrost cycles based on the sensor data as to how to keep the temperature and humidity at the optimal level. In addition to the other refrigerator components, for example, display panel and user interface, the PCB Main Assembly provides feedback and enables users’’ interaction. The PCB Main Assembly incorporates safety features of overload protection and temperature sensors to protect the refrigerator from damage and to protect the user.

Communication Protocols

Data can be communicated to other components through microcontrollers by communication protocols like UART (Universal Asynchronous Receiver Transmitter), SPI (Serial Peripheral Interface), and I2C (Inter Integrated Circuit).

UART is used to transfer real-time data from a microcontroller to external devices like display panels and temperature sensors.

There is a power of communication SPI and I2C for the communication of integrated circuits associated with the PCB Main Assembly for efficient data transfer and synchronization between components.

Troubleshooting and Maintenance

Common issues with the Samsung Refrigerator PCB Main Assembly include sensor failures, relay malfunctions, and power supply issues, which can affect the refrigerator's performance.

To solve PCB Main Assembly problems, we can use diagnostic methods, like running self-tests and checking the error code.

The assembly can stay longer depending on the main, such as cleaning dust and debris from the PCB and securing appropriate ventilation.

The PCB Main Assembly is an important component of the Samsung refrigerator systems since it organizes several functions to contribute to the overall efficiency of the refrigerator and food preservation. Fore-knowledge of the PCB Main Assembly and the way it is constructed can assist users in likely managing problems in their fridges.
