Color Coded GPIO headers

August 26, 2017

I came across this color coded GPIO header for the Raspberry Pi Zero from the Pi Hut. This can be really useful while prototyping a circuit. 5V pins are coded red, 3.3V pins are coded yellow, Ground pins are coded black.


It can help avoid connections to the wrong pin.


I usually refer to the GPIO pinout when I am connecting to the UART or the I2C interface. I always mix up the pin names. I wish the header had side labels like the Arduino.


Given the header height, I guess it is not practical to have labels. You can buy the headers from here.


I am exhibiting at the World Maker Faire (September 23 – September 24)

I haven’t been actively maintaining my blog these days. I recently moved to the Buffalo, New York area and settling down. I am willing to keep up with my blog posts. I have some great news to share with my readers.

My brother and I are going to be exhibiting at the World Maker Faire on September 23rd and 24th, 2017 in New York City. We are going to be showing off a DIY Personal Health Dashboard.  We have been working on a visual aid that motivates one to stay physically active.


I plan to share my progress of our dashboard through the different stages.


We look forward to seeing you there.
