Features

  • 3U 6HP Eurorack card
  • Arduino Pro Mini CPU
  • Drives recessed NeoPixel strip in top of Eurorack box
  • Daughtercard to ER-PROTO-02 card
    • Uses Front Panel and Controls card
  • RV1 = Mode knob
    • 4 modes: 3 rainbow, 1 white
  • RV2 = brightness
  • GATE input could be used to step between rainbow pattern
  • LED strip types (Ebay search)
