Hackaday Review

[Hackaday Full Review Pending]

NOTE: Unlike the WiFi Serial Transceiver Module w/ ESP8266, this small version has no built-in antenna.

ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.  It is super easy to use supporting both AT Commands (via UART / COM port), also NodeJS thru the NodeMCU firmware, as well as traditional embedded software development via SDK.  There is also awesome support for the ESP8266 using Arduino available from Adafruit.
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

This module with ESP8266 was recently featured in this Hackaday article.  Have a look also at @technolomaniac's workshop and projects based on the ESP8266 available on hackaday.io.
