The module provides four 2x6 female PMOD connectors. Two of the headers (P1 P2 and P2P3) are arranged to use as dual 12 pin PMOD. According to the standard on all four headers Pin 5 and 11 are connected to ground, 6 and 12 to 3.3V.

JTAG access to the SoC components is provided through the micro usb connector via the FTDI usb to UART bridge. Depending on the jumper J6 the JTAGSEL signal SW3 switches the JTAG interface to either the FPGA fabric TAP (open, high) or the Cortex-M3 JTAG debug interface (closed, low). JTAG signals are powered by 3.3V.
