Adafruit GPIO Reference Card for Raspberry Pi Model B+/Pi 2/Pi 3

The Adafruit GPIO Reference Card for Raspberry Pi Model B+, Pi 2, and Pi 3 is a simple tool that makes GPIO connections easier to understand. It gives you a clear pin reference directly on the board. Therefore, you do not need to keep checking pinout diagrams while working on your project.

The card slides onto the Raspberry Pi 2×20 GPIO header and stays easy to read during use. In addition, it is designed to help prevent incorrect installation. This is especially useful for beginners. However, it is also a great accessory for experienced makers who want faster setup and fewer wiring errors.

Each pin is labeled by function. For example, you can quickly identify I2C, IO, UART, SPI, and power pins. As a result, building and testing projects becomes much easier. You can also place female jumper wires on top while still seeing the printed labels.

The board uses a thin 0.8mm PCB design. Because of that, it stays lightweight and does not add bulk to your Raspberry Pi setup. Moreover, its compact size makes it a smart choice for workshops, classrooms, home labs, and electronics benches.

This version is made for the Raspberry Pi Model B+, Pi 2, and Pi 3. However, it does not fit the original Raspberry Pi Model B. Finally, its small size and clear layout make it a useful accessory for anyone who works with Raspberry Pi GPIO pins on a regular basis.
