README.md

Adapter PCB to support up to 3 panels

  • Supports up to three panel chains 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.
  • Open source KiCAD PCB EDA format.
  • (not very pretty layout, was just lazy and let the auto-router do it).
  • BOM:
    • 4x HCT245 in 20-SOIC (7.5mm package)
    • 4x 100nF ceramic capacitor
    • 1x 10kOhm resistor.
    • 3x 16pin IDC (=2x8) male receptible to connect the panels.
    • 1x 40pin female connector to connect to the RPi.
  • The FAB files are provided as active-3-fab.zip

The board is also shared on OSH Park.
