The Serial To WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The onboard ESP-12F ESP8266 module is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers!

The AT command set firmware in this module supports MQTT Client. MQTT (Message Queuing Telemetry Transport) is a lightweight IoT protocol working on TCP/IP stack. The publish/subscribe messaging protocol helps to provide capabilities to transmit or receive sensor data through MQTT broker. It is designed for efficient and robust machine-to-machine communication with a very small footprint.

Note: This module is designed for 3V Microcontroller ONLY.
