Hi @rorosaurus,

Great work on the PCB! I've used a board in connector 1 mode for some testing and just soldered a board in connector 0 mode and stumbled upon some clearance issues with the frame attached to the displays I have on hand:

There is simply not enough room to properly seat the PCB when the frame is present. I'm planning on 3D printing a stand that attaches to the frame of the display, so I would need to properly seat the PCB.

I'm using generic P3 displays sold on e.g. AliExpress such as these

Perhaps moving the connector pins way to the left (when viewing the board from the top seated on the PCB) could fix the clearance issues with frames. Some displays need around 8mm additional space according to my measurements while others need 5mm (only have a handful displays)

Also a power barrel jack might be worth considering for future revisions?

Thanks

Just a quick follow up:

I quickly remixed a bracket for a P3 display so that I could attach the PCB in output mode 1 to the back of the display even with stands mounted. Can be found here if anyone else needs this: https://www.thingiverse.com/thing:4818439

Power cables to be cut to size later ;)
