PCB Layout

Here are some screenshots from the signal layers of OpenRex PCB. The PCB has 10 Layers in total with through hole VIAs only. (Click to enlarge)

Add-on boards

The TOP OpenRex add-on board is also Raspberry Pi compatible. It may be used on the OpenRex SOLO version (with no or low profile heatsink). The BOTTOM add-on boards are larger. The plan is to support multiple add-on boards stacked on top of each other. It will require a lot of testing and playing.
