ESP8266 WiFi Module (ESP-07) เป็นบอร์ด ESP8266 ที่มามารถต่อเสาร์สัญญาณภายนอกเพิ่มได้ ทำให้ตัวอุปกรณ์รับสัญญาณได้ดีขึ้น

The ESP8266 is a highly integrated chip designed for the needs of an increasingly connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host applications or offload all Wi-Fi networking functions from another application processor.

The ESP8266 has powerful on-board processing and storage capabilities that allow it to be used with 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. The entire solution, including the module, is designed to occupy minimal PCB area.
