Overview
The Digilent PmodCON4 allows users to act as a transceiver with two RCA audio jacks.
1 FunctionalDescription
The PmodCON4 is able to route any GPIO based audio signal from one of its four input pins (pins 1 through 4 on
the 1×6 pin header) to either one of the RCA audio jacks via the jumper block present on each of the inputs.
2 InterfacingwiththePmod
The PmodCON4 is able to both receive and transmit audio (or other) signals to one of the two RCA jacks. However,
only one input/output pin can be attached to an RCA audio jack at a time. If two or more are tied to the same jack,
there is a chance that one output will be at a high voltage and the other output at a low voltage, effectively
shorting those two pins and potentially damaging the system board.

Since RCA jacks typically send or receive analog voltage signals, users can easily connect thePmodCON4 to either
an ADC or DAC module such as the PmodAD5 or the PmodDA4.
3 PhysicalDimensions
The pins on the pin header are spaced 100 mil apart. The PCB is 1.10 inches long on the sides parallel to the pins on
the pin header and 0.8 inches long on the sides perpendicular to the pin header.
