Introduction：

1. WiFi uses industrial-grade chip ESP8266, the module is ESP-13 with metal shield, strong anti-interference ability; 2. The standard pins are compatible with the main control boards such as Arduino Uno and Mega2560. Arduino and UNO are connected with a voltage conversion chip to make 3.3V and 5V compatible; 3. The serial port is controlled by a dual DIP switch, so that the expansion board can be used as an Arduino Uno expansion board alone or as an ESP8266 expansion board; 4. Real serial WiFi, Arduino program does not need any configuration; 5. Configure WiFi parameters and serial port parameters based on Web Server; 6, can be used as an independent ESP8266 development board, download the official AT instruction firmware, NodeMCU open source firmware, etc .; 7. Can be used as an independent Arduino Uno expansion board, all pins are led out. Technical specifications 1. Support wireless 802.11 b / g / n standards; 2. Support two working modes of STA / AP; 3. Built-in TCP / IP protocol stack, can configure a socket; 4. Support standard TCP / UDP Server and Client; 5, serial baud rate support: 1200/2400/4800/9600/19200/38400/57600/74800/115200 bps; 6, serial data bits: 5/6/7/8 bits; 7. Serial parity check: None; 8. Serial port stop bit: 1/2 bit; 9. Standard Arduino UNO, Mega pin pitch; 10. Draw Arduino Pin 2/3/4/5/6/7/8/9/10/11/12/13; 11. Lead ESP8266 GPIO 0/2/4/5/9/10/12/13/14/15/16 / ADC / EN / UART TX / UART RX; 12, RESET reset; 13, KEY button reuse configuration function; 14. Two-position DIP switch realizes Arduino and ESP8266 serial port extension switching; 15. WiFi working current: continuous sending: ≈70mA (200mA MAX), standby:
