Universal Controller Board v1.3

Note: development on Kicad boards should be done in the electronics/universal directory in subversion

Schematic

Changes (Done)

  • Add debug LED's to Tx and Rx (nophead)
  • Add debug LED's to min/max sensors (nophead)
  • Add ICSP Header (Eric Frias)
  • Add debug LED's to extra power transistors (Zach Smith)
  • Remove R7/R8 wire links (nophead)
  • Add ICSP header components (Eric Frias)

PCB Layout

TODO List

  • Slightly Enlarge holes on .100 headers
  • 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).
  • More space for heater transistor heatsink (ensure clearance on heater LED)
  • Avoid running high-amp power tracks through the board. Use multiple vias if transit is unavoidable.

General TODO

  • Test LED modifications on v1.2.1 board with 'green wire' mods.
