The module has the ability to run independent of a host controller.
The ESP8266 Serial/UART to WiFi module is a great way to connect your Arduino or other microcontroller projects to a WiFi network.
Create your next internet of things (IOT) project with affordable network connectivity by implementing this module into your design.
The ESP8266 has 3.6V max tolerant I/Os so you will need a logic level converter to connect it with higher voltage devices such as Arduino.
The ESP8266 requires 3.3V power so you may need a 3.3V voltage regulator to provide the correct voltage, depending on your setup.
