P-14 WiFi Module Combines ESP8266 with STM8S MCU with 802.11b/g/n is can be widely used in smart home and the Internet of things, for the user's physical devices connected to the Wi-Fi wireless network. The module built a powerful STM8003 chip, all the pins are all connected to the serial port and ESP8266 serial port connected, the user can write STM8 program, through the AT command to control the ESP8266 to achieve the vast majority of smart home and WIFI features. ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. The range of operation of this module is almost up to 3.7km! That means it can connect to a server over 3 km away! Great for robot applications that need remote control.
