    • LED1 - JP0 removes - connects to IO3
    • LED2 - JP2 removes - connects to IO7
    • LED3 - JP3 removes - connects to IO10
  • LED4 - JP4 removes - connects to IO11
  • LED Select jumpers (solder bridges)

Connectors[edit]

  • P3 and P4 marking is different on the Rev X1 board
    • These are the actual pin numbers

FPGA Board Pinout[edit]

  • Pin numbers on the FPGA card are marked on the silkscreen on the bottom of the FPGA board
  • Note that this is reflected when the card is installed onto the BASE board
  • The base board also mirrors the adjacent pins

P1, P2 - FPGA Female connector[edit]

  • Generally matches FPGA pinout
  • Exceptions
    • 3.3V from the FPGA card is not connected out of the FPGA card
      • 3.3V power pins on the Base board are provided by the 3.3V regulator on the Base board

P3 - Male header pins[edit]

  • Flipped from the FPGA pinout
  • Note that the physical pins on the schematic are reversed from the pinout on the card
  • Pin 1 from the FPGA is +3.3V
    • Not connected on the header pins
    • Base board is powered from the on-board 5V to 3.3V regulator

Retro-Computer (MultiComp) Map EP2 to EP4 card[edit]

  • Map EP2 to EP4 card
    • Maps EP4 I/O connections to the EP2 card used for Multicomp

Rev X2 Checkout[edit]

  • WIP

Rev X1 Checkout[edit]

  • Connectors are swapped
    • P3 and P4 Silkscreen is wrong
    • Power is OK since the two connectors have the same pinouts for power
    • Corrected silkscreen is as follows
