partycat led controller

Partycat is a small ESP8266-based controller for WS2812 LED strips.


  • Level-shifted GPIO pins, including one for a WS2812 strip
  • A footprint that lets you solder the end of the strip right to the board
  • WS2812 is on the I2S port, so it can use DMA using this hack (or the Arduino-compatible version)
  • Programming using a standard 6-pin FTDI cable (no onboard USB you wuss)

It's Party Time
