Adapter PCB to support up to 3 panels | ||
====================================== | ||
|
||
(work in progress) | ||
|
||
* Supports one panel for Raspberry PIs with 26 GPIO pins 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). | ||
