Six-Pin Accessory Headers R
Six-Pin Accessory Headers
The 6-pin accessory headers provide easy I/O interface expansion using the various
Digilent Peripheral Modules (see “Related Resources,” page 126 ). The location of the 6-pin
headers is provided in Figure 15-1, page 115 .
Header J1
The J1 header, shown in Figure 15-8 , is the top-most 6-pin connector along the right edge of
the board. It uses a female 6-pin 90° socket. Four FPGA pins connect to the J1 header,
J1<4:1>. 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 Figure 15-9 , is the bottom-most 6-pin connector along the right
edge of the board. It uses a female 6-pin 90° socket. Four FPGA pins connect to the J2
header, J2<4:1>. The board supplies 3.3V to the accessory board mounted in the J4 socket
on the bottom pin.
