Description:
1. WiFi uses industrial-grade chip ESP8266, and the module is ESP-13 with a metal shield, which has strong anti-interference ability;
2. The standard pins are compatible with main control boards such as Arduino Uno and Mega2560. The voltage conversion chip is used to connect Arduino and UNO to make 3.3V and 5V compatible;
3. The serial port is controlled by a two-way DIP switch, so that the expansion board can be used as an Arduino Uno expansion board alone or as an ESP8266 expansion board;
4. Serial WiFi, Arduino program does not need any configuration;
5. Configure WiFi parameters and serial port parameters based on Web Server;
6. It can be used as an independent ESP8266 development board to download official AT command firmware, NodeMCU open source firmware, etc.;
7. It can be used as an independent Arduino Uno expansion board, with all the pins leading
