Description:
This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands. The ESP8285 with 1 MB of built-in flash, allowing for single-chip devices capable of connecting to Wi-Fi. Many ESP-xx modules include a small onboard LED that can be programmed to blink and thereby indicate activity.
The ESP8266 supports APSD for VoIP applications and Bluetooth co-existence interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions and requires no external RF parts.
There are several antenna options for ESP-xx boards including a trace antenna, an onboard ceramic antenna, and an external connector that allows an external Wi-Fi antenna to be attached. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor.
Note: The ESP8266 Module is not capable of 5-3V logic shifting and will require an external Logic Level Converter. Please do not power it directly from your 5V development board.
