Product features:

  • The wifi is industrial-grade chip ESP8266, and the module is ESP - 13 with metal shield, which has strong anti-interference ability.

  • Standard pin compatible with the main control board such as Arduino Uno, Mega2560 , a voltage conversion chip is used to connect with the Arduino and Uno, which makes 3.3 V and 5 V compatible.

  • A serial port be used dual dial the code switch to control, makes the extension board can separately used as Arduino Uno extended board, and can also be used as ESP8266 expansion board.

  • Real serial WiFi, the Arduino program don’t need any configuration.

  • Based on the Web Server configuration wifi parameters and the serial port.

  • Can be used as an independent ESP8266 development board, download the official firmware the AT command, NodeMCU open-source firmware, etc.

  •  Can be used as independent Arduino Uno expansion board, pins all leads.
