GPIO Expanders

The Raspberry Pi features several digital GPIO (General Purpose Input/Output) pins operating at 3.3V logic levels. Connecting 5V devices directly to these pins can cause permanent damage to your Raspberry Pi.

Our Raspberry Pi GPIO expansion boards are designed to safely interface with 5-volt logic devices, making it easy to extend the functionality of your projects.

We offer a selection of digital input and output boards compatible with the Raspberry Pi and other single-board computers, ideal for robotics, automation, and electronics projects.
