Building

The gerbers folder has a zip file if you want to order your own PCB.

There is a bom.csv that contains all the parts and digikey part numbers you need

There's also an interactive_bom.html that is from the excellent InteractiveHtmlBom plugin

Known Issues

Rev 1

1. Battery connector is wired backwards
2. microSD footprint is backwards, so it is un-usable
3. Battery and battery charging to do not work. I plugged one in, immediatly smelled burning. Current theory is that I forgot a current limiting resistor on the LDO's EN pin, so too much current from battery (but not from USB).
