Pmod Connectors
Digilent Pmods provide various peripheral
functions. These can be as simple as buttons
or switches for inputs and LEDs for outputs, or
as complex as graphical LCD display panels,
accelerometers, and keypads.
All Digilent Pmods use either a 6-wire interface
or a 12-wire interface. The 6-wire interface
provides four I/O signals, power, and ground.
The twelve-wire interface provides 8 I/O
signals, two powers, and two grounds. The
signal definitions for the I/O signals as well as
the voltage requirements for the power supply
depend on the specific module.
The VmodMIB provides five 12-pin Pmod
connectors.
HDMI Connectors
The VmodMIB also provides four HDMI type-D
connectors to allow audio/video connections to
the system board. They use 19 pins and the
relationship between these pins and the signal
names from the VHDCI connector are
described in table 3. Each HDMI connector
has a jumper which can be used to select a 5V
source when shorted.
Also, data can be sent to the HDMI connectors
via an I
2 C bus from signals JE1/SDA and
JE2/SCL when the jumpers at J2 are shorted.
Keep in mind that all HDMI ports share signals
with Pmod ports. JA is shares signals with
JAA, JB with JBB, JC with JCC, JD with JDD.
All HDMI ports share pins with Pmod port JE,
which contains the I
2 C bus signals.
