The Pmod connector is a 2x6 right-angle, 100-mil female connector that mates with standard 2x6 pin
headers available from a variety of catalog distributors. The 12-pin Pmod connector provides two VCC
signals (pins 6 and 12), two Ground signals (pins 5 and 11), and eight logic signals. VCC and Ground
pins can deliver up to 1A of current. Jumper JP12 selects the Pmod Vcc voltage (3.3V or 2.5V) in
addition to selecting the VHDC voltage. Pmod data signals are not matched pairs, and they are routed
using best-available tracks without impedance control or delay matching.
On the Atlys board, the eight Pmod signals are shared with eight data signals routed to an HDMI type
D connector. The HDMI connector, located immediately beneath the Pmod connector on the reverse
side of the board, includes an I2C bus and conforms to the HDMI type D pinout specification, so it can
be used as a secondary HDMI output port. A type D to type A HDMI cable may be required, and is
available from Digilent and a variety of suppliers.
