MicroPixel Edge RGB LED Add-on Board for BBC microbit

MicroPixel Edge RGB LED Add-on Board for BBC microbit

Part of our range of microbit accessories and addons, the micropixel EDGE has 10  WS2812B (NeoPixel) RGB LEDs.
Each one of the 10 RGB LEDs are individually addressable which means you have full control to create complex lighting patterns.
Simply plug your microbit into the connector, upload your code using the neopixel library and you're good to go!
This little board goes great with our bat:bit which makes the whole thing compact and mobile.
The BBC microbit itself is not included - you will need one to get this product running and you can pick one up here!
