NodeMCU V3 ESP8266 CH340

NodeMCU is a small Arduino-compatible WiFi board ready to use in any IoT project. It is built around the well-known ESP8266 and exposes all its pins on the sides. It also offers other advantages such as the incorporation of an integrated voltage regulator, as well as a USB programming port. It can be programmed with LUA or through the Arduino IDE.

It has an extensive community and documentation that will allow you to connect your project to the outside world via WiFi connection.

Because it uses a CH340 USB converter, the operating system usually installs it automatically, although depending on the case, you may need to install the specific driver.
