With the release of the Digital I/O System for Raspberry Pi®, we’ve posted code samples on developer.opto22.com to read and write to I/O modules from your Raspberry Pi.

The website also has diagrams to show how the Carrier Board maps the Pi’s GPIO pins to I/O modules on a mounting rack, and a mapping overlay you can print and place over your Pi’s pins.

Opto 22’s Digital I/O System for Raspberry Pi lets you use a Raspberry Pi to switch real-world electrical loads like industrial motors and pumps, and sense status through industrial-grade sensors.

It’s ideal for prototypes, proofs of concept, and environments in which an industrially hardened controller is not required. You can use your favorite Pi-supported programming language and choose from a wide variety of digital I/O modules to fit what you want to do.
