ESP8266 Freezer Door [1]: Concept and first try. r/esp8266: ESP8266 WiFi Module Help and Discussion. These modules come in different form factors and pinouts. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The ESP8266-14 module has pins and connections on three sides of the board. Using an AT command set, any microcontroller with a UART can use the ESP8266 to. I would like to write down my experience regarding the communication between Arduino and ESP8266 UART WIFI shield in this article. Teensy-LC will be ideal for inexpensive "Internet Of Things" projects when paired with a ESP8266 Wifi module, which requires a fast hardware serial or SPI port.
