This card makes it incredibly easy to connect cables to the Raspberry Pi GPIO. It's a reference card that makes it really easy to see whether you've connected your cables correctly. In the Low Voltage version, we made some changes, including categorizing the pins into categories like I2C, IO, UART, SPI, and power.
At only 0.8mm thick, it makes a great keyring for Pi enthusiasts. Simply slide it onto the 2x13 GPIO header, then attach top-quality jumper cables as shown.
This version is compatible with the Raspberry Pi Model B
Please note that it does not work with the Raspberry Pi Model B+; however the B+ version is available at SAMM MARKET.
Please, note that we made a typographical error in Revision A! The pin labeled as #21 should be labeled as #27, and the pin below it should be labeled as #22.
