BitsyLED is a minimal firmware to drive RGB LED’s (WS2811, WS2812, NeoPixels, etc). It’s designed for anything RC but also can be used for other projects including Christmas lights, Lego’s, or even your real car.

This is the BitsyLED board - a small board powering an ATTINY84 that exposes 3 channels on a common RC signal layout (GND, 5V, DATA). The board itself can fit up to 5 range configurations each having 3 strands with 10 Led’s / strand.

Parts needed (Digikey.com): * ATTINY84 (Part ATTINY84A-SSURCT-ND) * Blue LED in 805 packaging (Part ‎150080BS75000) * Resistor in 805 packaging with value of 140ohms (Part RMCF0805FT140R) * Capacitor in 805 packaging (Part 587-1304-1-ND) - Diode in SOD-123 packaging (Part MMSZ5231B-TP)

The 1.2 board includes SMD pads instead of the drill pads and allows to either directly solder wires to the pads OR use 2.54mm spaced headers. As a convenience the Serial/SPI breakout on the bottom is aligned with the top pads so double row headers can be used.

This 1.2.1 board has a cleaner layout.
