Finally! Colour-coded GPIO pins! These 40-pin 2x20 male GPIO headers can be used on a Raspberry Pi Zero and are colour-coded to help you navigate GPIO pins. Never have to search for a ground pin again! Colour Scheme We've kept these nice and simple: * Red = 5V * Yellow = 3V3 * Black = GND * Blue = DNC (Reversed I2C) We also have a 5-pack of coloured GPIO headers, or just plain standard black versions if you'd prefer to keep it simple.
