If you live in the continental US and are interested in helping me Beta test a new product, send me an email to email@example.com. I am building up a couple of units for Beta test purposes.
I only need 2 or 3 testers. For your feedback on operation, recommendations for documentation, etc, you will get to keep the PI Hat board.
The board uses a TI LM 2596 switching power supply IC. The board has a HAT EEPROM, and a Maxim 1631A temperature sensor IC.
It is compatible with the Raspberry PI 3, and I have included an extra mounting hole which should allow mounting for with the Raspberr Pi Zero board.
You can find a photo of the board here, https://cloudmoves.com/ .
I look forward to someone reaching out.
