Pinout! The comprehensive GPIO Pinout guide for the Raspberry Pi.
This GPIO Pinout is designed to be both a quick, interactive reference to the Raspberry Pi GPIO pins, plus a comprehensive guide to your Raspberry Pi's GPIO interfaces. It also includes dozens of pinouts for Raspberry Pi add-on boards, HATs and pHATs.
Latest Pinout news
We've added a board explorer! Use it to find the pinout for a Raspberry Pi add-on board, or discover new ones. If you manufacture boards, we'd love to add yours too. You can contribute over on GitHub.
What do these numbers mean?
- BCM - Broadcom pin number, commonly called "GPIO", these are the ones you probably want to use with RPi.GPIO and GPIO Zero
- WiringPi - Wiring Pi pin number (shown as a tooltip), for Gordon Henderson's Wiring Pi library
- Physical - Number corresponding to the pin's physical location on the header
- Rev 1 Pi - Alternate BCM numbers for the original, 26-pin model "A" and "B" Pi
