If you orient your Pi such that you are looking at the top with the GPIO on the right and HDMI port(s) on the left, your orientation will match Pinout. Pin 1 is the only pin with a square solder pad, which may only be visible from the underside of your Pi. Pinout depicts pin 1 in the top left corner.

Rev 1 Pi - alternate GPIO/BCM numbers for the original, 26-pin model 'A' and 'B' Pi.

These are shown as a tooltip when you mouseover a pin. WiringPi - for Gordon Henderson's Wiring Pi library.These are the small numbers next to the header, e.g. Physical - or 'Board' correspond to the pin's physical location on the header.You'll use these with RPi.GPIO and GPIO Zero. GPIO - General Purpose Input/Output, aka 'BCM' or 'Broadcom'.If you manufacture boards, we'd love to add yours too.

Pinout has teamed up with Pimoroni to create a prototype board compatibility tool, check it out here! Explore HATs & pHATsĬheck out Pinout's board explorer! Use it to find the pinout for your Raspberry Pi add-on board, or discover new boards.

Thank you.If you love Pinout, please help me fund new features and improvements: Pinout also includes dozens of pinouts for Raspberry Pi add-on boards, HATs and pHATs. This GPIO Pinout is an interactive reference to the Raspberry Pi GPIO pins, and a guide to the Raspberry Pi's GPIO interfaces. Pinout! The Raspberry Pi GPIO pinout guide.
