Power and Communications Board v1.3

Note: development on Kicad boards should be done in the electronics/powercomms-1.3 directory in subversion

Already Done

  • Add debug LED's to TTL Tx/Rx lines (nophead)
  • Add debug LED's to RS232 Tx/Rx lines (nophead)
  • Add RJ11 connectors to Tx/Rx (Zach Smith)

TODO List

  • Layout board in Kicad
  • Make .100" holes slightly bigger
  • Test LED modifications on v1.2.1 board with 'green wire' mods.
  • give the .100 connectors a proper silkscreen for Tx/Rx as well as power.
  • The holes for the C6 capacitor are slightly too close together so the legs have to be bent to fit into the holes and so it isn't seated flush with the board (or in my case even level).
  • Fastener holes: ensure clearance fit for 1/8" (3.125mm) diameter shank (Imperial equivalent of M3). Dia 3.5mm should do it.
  • Fastener washer space: ensure circuits avoid the radius of an M3 washer on the fastener holes (metal washers might short the circuit).
