NodeMCU ESP8266 V3 4MB Development Board WiFi (OT107-B54)

This is the large ESP8266 development board with onboard WiFi and is ideal for IoT (Internet Of Things) projects because it has onboard WiFi. Please note that it does not fit well on 1 breadboard. You will have to connect 2 breadboards.
This ESP8266 can also be programmed via the Arduino IDE. Watch the Youtube video above for the installation of that board in the Arduino IDE.

The NodeMCU ESP8266 V3 4Mb CH340G with WiFi is an excellent choice for creating great IoT projects. This open-source board features an integrated ESP8266 chip, running at 40MHz and with enough pins to cover all the Wi-Fi needs of standard IoT projects. Thanks to the open-source firmware, you can improve the kit with user-made updates and upgrades. This, combined with the board’s smart features, makes the NodeMCU a great starting point for prototyping and developing your own IoT devices. This version of odemcu V3 features the CH340G chip instead of the CP2102 serial chip to save costs. If you are interested in getting started with IoT development, this board will definitely interest you.
