ESP8266 Serial WiFi Expansion Board Module for Arduino
The ESP8266 Serial WiFi Expansion Board Module is a shield that allows the Arduino to connect to WiFi networks easily using the ESP8266 ESP-12E UART Wireless WIFI Shield TTL Converter. It eliminates the need for a complex circuit with multiple components and wires to link an ESP8266 to the Arduino. Just plug the board into the Arduino, set the DIP switch path according to the shield’s operating mode, and program the Arduino to access WiFi networks. Moreover, the board can work independently of the Arduino, as it has all the pin-outs of the ESP-12E available.

Frequently Asked Questions
Can I use this board without an Arduino?
Yes. All ESP-12E pins are broken out on the shield, so you can power it at 3.3 V and connect to any USB-TTL adapter or microcontroller for standalone WiFi applications.
How do I switch between AP, Station and AP+Station modes?
Set the mode DIP switches on the shield as labeled: one position for AP, another for Station, and both engaged for simultaneous operation. No soldering or code changes are required.
What is the procedure to change the processor clock speed?
Use the AT+CIOBAUD or SDK configuration commands in your serial terminal to switch the ESP8266 between 80 MHz and 160 MHz operation. Ensure sufficient power is supplied when running at the higher frequency.
