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.
