A colour-coded 2×20 pin header for the Raspberry Pi Zero and Zero W that makes it easy to identify pin functions at a glance. Each pin group is colour-coded so you can quickly find power, ground, and GPIO pins without counting or consulting a pinout diagram.
Colour Coding
- Red – 5 V
- Yellow – 3.3 V
- Black – GND
- Blue – Do Not Connect
- Green – GPIO
Note: Soldering is required to attach this header to your Pi Zero. Only the Pi Zero and Zero W ship without a pre-soldered header — this header is not compatible with Pi models that already have header pins attached (Pi 2, 3, Zero WH).

Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- 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.
