• ESP8266 ESP-14 WiFi Serial Transceiver

This WiFi serial transceiver module (ESP-14) is based on ESP8266 SoC. The SoC has Integrated WIFI communication IC and STM8003 micro-controller (8-bit MCU @ 16 MHz with 1KB RAM, 8KB flash, and 128 bytes EEPROM) with TCP/IP protocol stack, making it highly useful in applications of Internet of Things (IoT). 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.

ESP-14 has a built in PCB-printed antenna, 16GPIO pins, and UART (Rx,Tx) pins for communication with other devices.

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 (about the same size as the ESP-12E module).
