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
