Odseven Raspberry Pi 2X20 Double Row Pin Male Colour-coded GPIO Header for Pi Zero
Colour-coded GPIO pins that make locating that ground or power connection you need super simple!
These 40-pin 2x20 male headers from our friends at ODSEVEN can be used on a Raspberry Pi Zero and are colour-coded for your prototyping convenience.
You'll never have to search for a ground pin again!
The colour coding is nice and simple:
Red = 5V
Yellow = 3V3
Black = GND
Blue = DNC (Reversed I2C)
For hard-mode try installing the header the wrong way round and throwing away your normal pin reference! ;-)
