Pmod2rpi
About the Pmod2rpi PCB
Pmod2rpi is an open source PCB design by fm4dd, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 65 × 56 mm, with 36 components from 18 distinct parts.
Other key parts include the CAT24C32WI-GT3, SeeeduinoXIAO and PI5A100QEX. By type, the board carries 9 test points, 6 resistors, 3 ICs, 3 switches, 3 inductors and 2 capacitors.
From the project
PMOD adapter interface board for the Raspberry Pi GPIO, adding 4 PMOD connectors to the system.
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 range of input/output modules.
