The ESP8266 Serial WIFI Wireless Transceiver Module is a system on a chip (SOC) Wi-Fi microchip for Internet of Things (IoT) applications produced by Espressif Systems.

The ESP8266 module enables microcontrollers to connect to 2.4 GHz Wi-Fi, using IEEE 802.11 bgn. It can be used with ESP-AT firmware to provide Wi-Fi connectivity to external host MCUs, or it can be used as a self-sufficient MCU by running an SDK. The module has a full TCP/IP stack and provides the ability for data processing, reads and controls of GPIOs.


Given its low cost, small size and adaptability with embedded devices, the ESP8266 is now used extensively across IoT devices. It is always a popular choice for IoT developers and manufacturers. 


It has many GPIOs. With the help of  a SDK and various libraries, you can build your own firmware and use these GPIOs as arduino pins, and it makes external microcontrollers unnecessary.
