The Raspberry Pi GPIO Cheat Sheet was created by Pimoroni and Cyntech Components to aid with prototyping using the Raspberry Pi.
It is a fantastic way to educate those new to GPIO interfacing on the Raspberry Pi as to what it is capable of and what the various pins do. However it also doubles as a useful reference guide to avoid any accidental errors caused by plugging something into the wrong GPIO pin – great for beginners and pros alike!
So if you want to avoid having to search for Raspberry Pi pin and prototyping info on the internet again, or you just want to learn a little more about how the GPIO works then the Raspberry Pi Cheat Sheet is for you. Print it out and keep it to hand on your desk, or why not hang it on your classroom or computer cluster wall?
