When it comes to the Raspberry Pi, building your Pi project starts with a game plan and designing your plan starts with knowing exactly which GPIO pin does what. That’s where tools like our GPIO pinout article or the those offered by Pinout.xyz come into play.
Run by Pimoroni Developer Phil Howard, Pinout.xyz houses all sorts of useful GPIO charts and interactive tools for makers to reference while building their projects. Not only do they have every Raspberry Pi GPIO you can think of, but they also have quite a few pinout charts for Raspberry Pi accessories like HATs, boards, and pHATs.
