ESP8266 ESP-12F WiFi Module

Note: This ESP8266 ESP-12F module is an upgrade to the ESP-12E. It is fully pinout and software compatible with the ESP-12E. This new design features a four-layer PCB and improved antenna layout which increases the modules range.

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.
