Adapter PCB to support up to 2 panels

  • Supports one panel for Raspberry PIs with 26 GPIO pins and two panels for newer plus models and Raspberry Pi 2 that have 40 GPIO pins.
  • Uses HCT245 to level shift signals from 3.3V to 5V and shield the Raspberry Pi GPIOs from overloading.
  • This supports two panels and provides convenient breakouts for I²C and the serial interface.
  • Open source KiCAD PCB EDA format.
  • If you are interested in connecting three RGB panels, check out the Active-3 board (it won't support the serial intefaces though).

For multiple parallel boards to work and using the I2C and serial interface you have to uncomment

 #DEFINES+=-DSUPPORT_MULTI_PARALLEL   # remove the '#' in the begging

in lib/Makefile.
