The upload procedure for ESP8266 boards is a little different from a standard Arduino procedure. Most Arduino’s will automatically reset when a new program is being uploaded, and will automatically enter programming mode. On some ESP boards you have to manually enter programming mode, and on the bare-bones modules, you even have to reset them […]

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
In my previous blog ESP HomeKit SDK – Flash I showed you How to Use a ESP as a HomeKit device. Now there is a new version on the market. About In 2015 the ESP8266 took the embedded IoT world by storm. For less than a few bucks, you could get a programmable, WiFi-enabled microcontroller
