GEC02-PWB(A)A - bootleg

  • A hardware bootleg of the GEC02-PWB(A)A PCB
  • Runs original base microcontroller and FPGA firmwares
  • Key differences
    • Red dip-switches
    • Molex 4-pin power connector
  • Important note regarding power connector
    • If power connector is mounted correctly (on the top PCB layer), +5V and +12V are swapped (!!!). You need adapter cable that swaps the two pins in order to power it correclty by any standard PC power supply
    • If the connector is mounted on the bottom of the PCB ("turned around"), the pins for +5V and +12V are correctly mapped to the molex connector
