Passive 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.
  • This board is passive, so it does not need any more components than the connectors. If you have trouble with erratic pixels or need to connect long cables, then level shifting and buffering might help; check out the active boards in this case.
  • This supports two panels and provides convenient breakouts for I²C and the serial interface.
  • Open source KiCAD PCB EDA format.

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.
