The RasPiO® GPIO Ruler is the ideal quick reference for RPi.GPIO hacking on the Raspberry Pi in Python. Slip it over your Raspberry Pi GPIO header for easy to read pin labels.

The port labels are relevant to Raspberry Pi models 3, 2, B+, A+, and Zero. It's a great little tool to drop into your Maker's kitbox or pencil case.

  • Includes basic RPi.GPIO code examples
  • Labels each GPIO pin number and function
  • Can be used as a ruler (cm/inches)
  • 15cm/6in long
  • Portable, flat, goes "twang" when you hang it over a desk and flick it.

NOTE: Raspberry Pi not included

Jargon buster

Plain-language definitions for the technical terms used above.

GPIO
General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
