ESP32 Dev Kit PCB now on OSH Park

[BrookeDot]

As has been discussed here, I also put together a custom PCB for this OBEGRÄNSAD project. For those in the US the board can be ordered at OSH Park:

Or the design files here: https://github.com/BrookeDot/obegransad-pcb

Disclaimer: This is V2 of the board which has not been tested however it should fix a few minor issues that were present in the earlier V1 board which I have tested.

The microphone has not been tested.
