WiFi Shield SparkFun - ESP8266 Product Description This is the WiFi Shield SparkFun - ESP8266. The SparkFun ESP8266 WiFi Shield is an Arduino compatible shield for the ESP8266 WiFi SoC — a leading platform for Internet of Things (IoT) or WiFi-related projects. There are a variety of designs based around the ESP8266. If you just have an Arduino project that needs an inexpensive gateway to the Internet, the ESP8266 WiFi Shield does almost everything from turning on an LED to posting data and much more. The ESP8266 WiFi Shield comes pre-flashed with an AT-command firmware, so it can be controlled by any UART, but it also breaks out and provides command access to all of the ESP8266's I/O. Since this is an Arduino shield, it makes it easy to attach to any development board that utilizes the Arduino R3 layout. Product Specs: Arduino R3 Layout Wi-Fi Direct (P2P), soft-AP 802.11 b/g/n Integrated TR switch, balun, LNA, power amplifier and matching network Integrated TCP/IP protocol stack Integrated PLLs, regulators, DCXO and power management units Integrated low power 32-bit CPU could be used as application processor
