From the project

LED Strip Driver PCB

A 16x WS2812/SK6812 ledstrip driver for my LED ball with 900 SK6812 LEDs.

Essentially a clone to the awesome fadecandy board, but with a faster MCU and a second buffer chip connected to PORTC bits 0-7, allowing me to drive 16x80 RGB chips, or 16x60 RGBW chips.
