Adafruit GPIO Reference Card for Raspberry Pi Model B
9 units available with a short lead time.
The Adafruit GPIO Reference Card makes it easy to identify and connect wires to the Raspberry Pi's GPIO header. This ultra-thin (0.8 mm) card slides directly onto the 2×13 GPIO header, labelling each pin by function — including I²C, UART, SPI, power, and general I/O — so you can wire up your projects with confidence.
Licensed from Low Voltage Labs and updated by Adafruit with grouped pin categories, this reference card is a handy tool to keep at your workbench. Plug female jumper wires on top of the card to make connections while keeping the pin labels visible. It also makes a great keychain for Raspberry Pi enthusiasts.
