PMOD is a 6-pin or 12-pin header interface with 2.54mm pitch. It is defined by Digilent and intended for slow 3.3 V signaling like UART, SPI and I2C.
We introduce an additional convention where the middle pins can be used for connecting analog signals.
- 6-pin variant: Middle two pins (3, 4) used for analog
- 12-pin variant: Middle four pins (3, 4, 9, 10) used for analog
This covers the use case of two-axis joysticks:
