I am trying to wire a wearable that will be a 2D matrix pattern. It’s a coat, with a large single vent. The wiring diagram I am hoping to do is attached. Is it possible? This would obviously be (much) easier as a traditional column-based snake, but due to the design of the LEDs, that isn’t possible. (The LEDs are at 4" offsets pre-wired, and I want the “rows” to be only 1" apart from each other).*
Here’s a wiring diagram for what I want; Yellow is LEDs, Red/Blue is data+power, red is just power.
- Just for fun: Here’s the LEDs I bought – 10M 20M Christmas Wedding Party Decoration Light WS2812B SK6812 Pixels RGB LED Fairy String Addressable Individually USB DC5V|Lighting Strings| - AliExpress – they’re a REALLY cool product and form factor, but I wish they were 2" offsets not 4" offsets. If anyone has seen that, please let me know. They come pre-wired to some weird esp8266 (probably? with some unknown firmware? (I haven’t disassembled it yet) with a remote and USB power, but you can (and I already have) cut that off and wired onto a PixelBlaze.
