Adapter PCB to support up to 3 panels ====================================== * Passive board. Simple, but might need to define `RGB_SLOWDOWN_GPIO` if you see glitches. Consider using the [active board](../active-3) in that case. * Only really advisable, if the LED panels have 74HCT245 (as opposed to just 74HC245) in their input stage, because then they can deal properly with the 3.3V logic levels coming from the Pi. * Supports up to three panel chains for newer plus models and Raspberry Pi 2 that have 40 GPIO pins. * Open source KiCAD PCB EDA format. * (not very pretty layout, was just lazy and let the auto-router do it). * The FAB files are provided as [passive3-rpi-hub75-adapter-fab.zip](./passive3-rpi-hub75-adapter-fab.zip) This board is [shared on OSH Park][osh-passive3] (not affiliated). ![Preview][rendering] [rendering]: ../../img/passive3-pcb.png [osh-passive3]: https://oshpark.com/shared_projects/FNAtZUsP
