First demo PCB board, single-side with 3 jumpers. It’s freshly exposed and ready for drilling. I used a copper board I had laying around, it was a bit scuffed so excuse the pockmarks.
I’ll expose the double-sided version later this week, after I hit the electronics store.
The rpi-pwrbtn repository on GitHub includes the double sided board schem and the MCU code: https://github.com/gamaral/rpi-pwrbtn
