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.\n\nLicensed 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.\n\nKey Features\n\n\nPin Identification at a Glance – Pins grouped by function: I²C, UART, SPI, power, and GPIO\n\nUltra Thin – Only 0.8 mm thick, slides onto the header without adding bulk\n\nFool-Proof Design – Can only be installed in the correct orientation\n\nWorks with Jumper Wires – Plug female jumper wires on top of the card for easy connections\n\n\nIdeal For\n\nQuick GPIO pin reference during prototyping\nRaspberry Pi workshops and classrooms\nKeeping pin assignments visible while wiring\n\n\nPackage Contents\n\n1× GPIO Reference Card for Raspberry Pi Model B\n\n\n\nWarning: This card is designed for the Raspberry Pi Model B (original, with 2×13 header) only. It is not compatible with the Raspberry Pi Model B+, Pi 2, Pi 3, Pi 4, or Pi 5 which use a 2×20 header.\n\n\n\nNote: On Revision A of this card, the pin labelled #21 should read #21/27, and the pin below it should read #22.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":9151,"title":"Default Title","sku":"AF-2262","price":5.0,"compare_at_price":5.0,"on_sale":false,"in_stock":true,"available_quantity":10,"option1":"Default Title"}]}
