PMOD2RPI is a PMOD-compatible Interface Board for the Raspberry Pi B-type GPIO connector. It provides a total of four PMOD connectors to run PMOD-compatible modules on the Raspberry Pi. This board is compatible to PMOD interface standard v1.3.1 by Digilent Inc. The PMOD (peripheral module interface) standard enables simple plug-in connectivity between FPGA or microcontroller development boards, and a wide range of input/output modules.
While all connectors provide digital IO, they also double as serial bus connectors for I2C and SPI modules. To aid troubleshooting, a set of Keystone miniature testpins can be fitted to create access for oscilloscope and DMM monitoring. A Seeeduino XIAO footprint has been added to additionally drive two of the four PMOD's, or to communicate with the RPi. The XIAO Cortex-M0 MCU is optional, and it can operate with the board "standalone", if needed.
