Based on ESP-12E prototype design
Inside adds STM8S003F3P6, STM8S can control ESP8266 by AT commands. The module is a complete STM8S MCU, can operate WIFI via STM8 microcontroller programming..
Very compact package size and ultra-low power technology
Can be widely used in smart home network and IoT, for connecting the device to the user’s physical Wi-Fi wireless network for Internet or LAN communications, networked functions.
The module is built into a powerful STM8003 chips, all the pins are lead out, and the serial port from STM8003 is connected with ESP8266
You can write STM8 program, ESP8266 implementation of most of the smart lamp home and WIFI things through AT command control Features.
