- 2 RCA audio jacks
- Receive and transmit audio signals
- Jumper blocks to easily adjust signal routing
- 6-pin Pmod connector with GPIO interface
The Pmod CON4 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.
Interfacing with the Pmod
The Pmod CON4 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.

|Header J1||Jumper Headers|
|Pin Number||Description||Jumper Settings||Description|
|1||Input P1||J2||The J2 RCA jack will receive this input|
|2||Input P2||J3||The J3 RCA jack will receive this input|
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.
