Product Overview
The T-Type GPIO Expansion Board is an essential accessory for Raspberry Pi makers, students, engineers, and IoT developers. It breaks out all 40 GPIO pins from your Raspberry Pi onto a clearly labeled expansion board that plugs directly into a standard breadboard.
Combined with the included 40-pin ribbon cable, this expansion kit makes it easier to build circuits, connect sensors, interface modules, and develop complex electronics projects without the confusion of directly wiring the Raspberry Pi GPIO header.
Whether you’re learning electronics, prototyping IoT devices, building robots, or developing automation systems, this GPIO expansion board provides a cleaner, safer, and more organized development environment.
