The day after Christmas, we got the assembled boards from Elecrow by DHL! The shipment took longer to get here than usual, but this was not surprising given the holiday shopping craziness.
Anyway, the boards are here, and they turned out great! We have already uploaded the bootloader and did the basic testing, which worked fine.
We now have to follow up by soldering some connectors which were not included as part of PCB assembly, uploading the firmware, and doing a full test of all the peripherals supported by RoverWing library. We will keep you posted!
