The ESP32 chip comes with 48 pins with multiple functions. Not all pins are exposed in all ESP32 development boards, and there are some pins that cannot be used. There are many questions on how to use the ESP32 GPIO’s. What pins should you use? What pins should you avoid using in your projects? This blog
For those that starting with the ESP modules, I have made some pinout diagrams, their functions and how to use them. The ESP8266 12-E chip comes with 17 GPIO pins. Not all GPIO’s are exposed in all ESP8266 development boards, some GPIO’s are not recommended to use, and others have very specific functions. With this
