Nyancat PCB KiCad project:
The footprints of this project had been modified.
- SW_SPDT_PCM12 removed mechanical pin
- LED_WS2812B_mini3535 larger pads than original footprint
BOM: WS2812B-3535 x 7 ATTINY85 x 1 0.1uF 0805 cap x 1 slide switch smd x 4 jst-ph 2pin x 1
Arduino sketch: Based on Adafruit's rainbow chaser. Use J1 pads to program ATTINY with ICE programmer or Arduino ISP.
