Header J1
The J1 header, shown in
the board. It uses a female 6-pin 90° socket. Four FPGA pins connect to the J1 header,
FX2_IO<4:1>. These four signals are also shared with the Hirose FX2 connector. The board
supplies 3.3V to the accessory board mounted in the J1 socket on the bottom pin.
Header J2
The J2 header, shown in
edge of the board. It uses a female 6-pin 90° socket. Four FPGA pins connect to the J2
header, FX2_IO<8:5>. These four signals are also shared with the Hirose FX2 connector.
The board supplies 3.3V to the accessory board mounted in the J2 socket on the bottom pin.
