Comparing the esp8266 with the available wifi solutions in the market, it’s a great option for anyone interested in making cool Internet of things-based projects at home or office. It’s costing a few dollars and is easy to integrate with any project very easily.
Esp8266 wifi module-based microcontroller comes in a wide variety of versions as shown in the above figure.ESP-12E or Nodemcu is the popular and the most commonly used ESp8266 based development board. We highly recommend the makers to use the NodeMCU kit, it’s one with a Built-in programmer and lots of GPIO. Thee BUilt in programmer board help to upload the program easy to the microcontroller
The most widely used ESP8266 development boards are the ESP-01, NodeMCU Kit, and the Wemos D1 Mini. We’ll show you the pinout for those boards. If you’re using another development board for project works, make sure you have the right pinout configurations
