I was not going to design a PCB for this, but then the nice people at PCBWay reached out and offered to make some for free.   So after failing to get Eagle running, a installed KiCad and knocked up a quick PCB. I decided to add a USB adapter based on the CH367 breakout board (similar to Albireo)

I now have the boards back from PCBWay and they look great. I'm waiting on some new edge connectors before I can build them up and test them. Once I have confirmed it works, I will update github
