We have a slightly revised design in the works for the card, and during that assembly process, we’ll be working on better assembly documentation on our github. Once we get the boards in and validate them, we’ll package it all into a new release for you guys. It will have protections against plugging in >5V into Vo on the connector, but otherwise is electrically identical to the old design. We will also be validating UART on the card, since we now have the switch to make that possible.
