Adapter PCB to support up to 3 panels | ||
====================================== | ||
|
||
* 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. | ||
* 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). | ||
|
||
For multiple parallel boards to work, you have to uncomment | ||
|
||
#DEFINES+=-DSUPPORT_MULTI_PARALLEL # remove the '#' in the begging | ||
|
||
in [lib/Makefile](../../lib/Makefile). | ||
|
||
* BOM: | ||
- 4x HCT245 in 20-SOIC (7.5mm package) | ||
- 4x 100nF ceramic capacitor | ||
- 3x 16pin IDC (=2x8) male receptible to connect the panels. | ||
- 1x 40pin female connector to connect to the RPi. | ||
You can [buy the board from OSH Park][osh-active3]. | ||
