We all love to build IoT projects based on ESP32 boards because it has lots of GPIO pins to play. Many ESP32 lovers like me face a problem selecting appropriate GPIO pins or which pins to avoid for their projects.
We have wasted many hours on an ESP32 project due to the selection of the wrong GPIO pin and, we don’t want you all to be making the same mistake.
Therefore we have created this easy-to-use guide, simplifying the ESP32 GPIO selection process. If you use a bar ESP32 module in your project, this guide will be a handy tool for you.
