Coming soon - A NeoPixel to RGB analog strip converter 🔴🟢🔵
We often work with 'true analog' LED strips (https://www.adafruit.com/search?q=analog+LED), with 1-3 channels of RGB or White LEDs. Controlling these takes a bit of wiring since they almost always need 12VDC and driver FETs. To make our lives easier, and maybe even some customer's too, here's a STEMMA board (https://www.adafruit.com/product/3893) that can convert a NeoPixel signal using a WS2811F to three AO3406 N-channel FETs (https://www.digikey.com/short/438tn2hb) that are high efficiency and can sink a chunk of current. There's a 3-channel 74LVC3G14 (https://www.digikey.com/short/tqq3tm3m) inverter to convert the WS2811 output signal, open drain, to the NFETs. 5 terminal block ports allow easy wiring of the +12V, ground, and RGB common-anode channels. Unfortunately, the WS2811 does not support 4 channels, so this won't work for RGBW strips. Still, folks often need 1 or 3 channels!

NeoPixel to RGB common anode converter testing
we're often working with 'true analog' LED strips (https://www.adafruit.com/search?q=analog+LED), that have 1-3 channels of RGB or White LEDs. and controlling these takes a bit of wiring since they almost always need 12VDC and driver FETs. to make our lives easier, and maybe even some customer's too, here's a STEMMA board (https://www.adafruit.com/product/3893) that can convert a NeoPixel signal using a WS2811F to three AO3406 N-channel FETs (https://www.digikey.com/short/438tn2hb) that are high efficiency and can sink a chunk of current. there's a 3-channel 74LVC3G14 (https://www.digikey.com/short/tqq3tm3m) inverter in between to convert the WS2811 output signal which is open drain, to the NFETs. 5 terminal block ports allow for easy wiring of the +12V, ground, and RGB common-anode channels. unfortunately the WS2811 does not support 4-channel so this won't work for RGBW strips…but there's a lot of times folks need 1 or 3 channels!
