1.  Embedded Wi-Fi module Overview:
WT8266-S1 Wi-Fi module is a low consumption, high performance embedded Wi-Fi network control module
designed by Wireless-Tag. It can meet the IoT application requirements in smart power grids, building automation,
security and protection, smart home, remote health care etc.
The module's core processor ESP8266 integrates an enhanced version of Tensilica's L106 Diamond series 32-
bit processor with smaller package size and 16 bit compact mode, main frequency support 80 MHz and 160 MHz,
support RTOS, integrated Wi-Fi MAC / BB / RF / PA / LNA, on-board PCB antenna.
The module supports standard IEEE802.11 b / g / n protocol, a complete TCP / IP protocol stack. Users can
use the module to add networking capabilities for existing equipment, also can build a separate network
controller.
