There are a bunch of things to fix:

  • Alignment holes for SW1 (the slide switch) isn't correct. We're forced to snip off the mounting pins right now.
  • Footprints for S3 and S4 are definitely not correct, they're way too small. Also considering going a through-hole for these switches.
  • Add in a 5.6k ohm resistor in line with the TX and RX UART lines from the STLINK3 in order to kill phantom power to the DUT.
  • Move diode D1 away from FFC connector J1, so that FFC is easier to open.
  • Make slightly larger, or add tabs for small rubber feet.
