This project is inspired by #PIXIE - Chainable, Dual 5*7 Micro-LED Displays! 

@Lixie Labs did a great job of writing Firmware for the Attiny and building the whole Environment.

Some main Features:

  • compatible to Pixie
  • can use same Firmware on the Module
  • can use same Library to control them
  • using discrete LEDS instead of Dot Matrix Module
  • compatible Pin header but with some additional pins fore easier chaining.
  • Can be also Mixed with PIXIE in same chain
