I set myself some rules:
- must be smart: so at least some i2c communication
- should have a PCB - plus for not extreme design rules
- no single LED
- must have some kind of blinky
- mus use standard SAO header, although 4pin Variant is fine for me
This will be fun to assemble... There are two 'frames' around the actual PCB. One from the manufacturer and one custom by me to get castellated holes on all four corners the PCB needs to get cut an sanded down
So you can finally mass produce on a MHP30. Amazing. Love it
