The comprehensive Raspberry Pi GPIO Pinout guide now with Raspberry Pi Model B+, Raspberry Pi 2 and Pi Zero.
This GPIO Pinout is designed to be both a quick-reference and a comprehensive guide to your Raspberry Pi's GPIO pins.
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's Wiring Pi library
- Physical - Number corresponding to the pin's physical location on the header
Raspberry Pi Zero
With the launch of the Pi Zero bringing Raspberry Pi into the hands of so many more people, we're pushing Pinout a little further with some visual tweaks and categorised menus to help you find what you need.
Raspberry Pi 2
To celebrate the launch of the Pi 2 and the new Pi-enthusiasts it'll bring, Pinout has been updated to be cleaner, more comprehensive and more accurate and will continue to be improved.
Raspberry Pi Model A+ and B+
Now that the Raspberry Pi Model B Plus is here, I've updated Pinout with the 14 extra pins you'll find on your shiny new board.
Raspberry Pi Model "A" and "B"
Pinout was originally designed for the old 26-pin Raspberry Pi models, you'll see the outline of this original header displayed on the left in a slightly darker shade. If you click a pin you'll see details of its BCM pin assignment on the original Rev 1 Pi.
