1. Overview
ESP8266-S1 Wi-Fi module is a low consumption, high performance Wi-Fi network control module designed
by Hysiry. 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 32bit 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 to existing devices, but also to build an independent net
work controller.
