new pcb testing

meshO PCB v1

The new PCBs arrived a couple of weeks ago but it’s taken quite a while to move the firmware to the new microprocessor/hardware and test that everything works.

**The good news is that all the components do work! So these boards can be used to build more meshO devices… **

but, there are a few minor issues that will need to be fixed for the next run:

  • the USB connector pins are backwards (easy to fix by swapping the pins on the plug)
  • the UART RX and TX pins are backwards (fixable in firmware)
  • the LEDs are all red (fixable for the next run by changing the hardware descriptors so that the PCB manufacturer uses different LEDs)
  • some of the silkscreens are not right (doesn’t affect the hardware)
