This is ESP8266 SOC is a TTL level serial to WiFi Transceiver module with PCB trace antenna. This ESP-01 type module communicates at 115200 baud. The module breaks out all necessary pins of the chip to a 2x4 pin header with 0.1" pitch.The ESP8266 supports 802.11 b/g/n networks as Access Point, Station and both at the same time. ESP8266 is a brand new low-cost WiFi chip from Espressif which allows you to easily connect your project to the Internet of Things (IOT) with a simple UART AT command interface. ESP8266 has powerful on-board processing and storage capabilities that allows it to be integrated with different sensors and other application specific devices through its GPIOs.
