ESP-14 ESP8266 WiFi Module
ESP-14 overview
ESP-14 ESP8266 WIFI module is a low-cost communication and control module, built-in ESP8266 WIFI communication IC and STM8s003F3P6 microcontroller. ESP-14 module has a built-in powerful STMs8003F3P6 chip, using which users can write STM8 programs and functions, through the AT command control WIFI Internet capability. The module offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or offload all Wi-Fi networking functions from another application processor.
ESP-14 high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including the front-end module, is designed to occupy minimal PCB area. The module can handle all the necessary overhead for communicating with your network. Such as TCP/IP stack and communicating with your 802.11 networks.
