ESP8266 ESP-13 Wifi Shield

1, WiFi uses industrial chip ESP8266, module ESP-13 with metal shield, strong anti-interference ability;

2. Standard pins are compatible with main control boards such as Uno and Mega2560. In UNO connection, voltage conversion chips are used to make 3.3V and 5V compatible.

3. The serial port is controlled by a two-way switch, so the expansion board can be used only as an Uno expansion board or as an ESP8266 expansion board.

4, the real serial port WiFi, the program does not need any configuration;

5, Configure WiFi parameters and serial port parameters based on the web server.

6. It can be used as an independent ESP8266 development board, for downloading official AT instruction firmware, NodeMCU open source firmware, etc.

7, Can be used as an independent Uno expansion card, pin all the cables.

Technical specifications:

1, Support wireless 802.11 b/g/n standard;

2, support STA/AP two working modes;

3, Built-in TCP/IP protocol stack, can configure a socket;

4, Support standard TCP/UDP server and client;

5, Support serial port baud rate: 1200/2400/4800/9600/19200/38400/57600/74800/115200 BPS;

6, serial data bit: 5/6/7/8 bit;

7, serial parity check: none;

8, serial port stop bit: 1/2 bit;

9. Standard UNO and Mega pin spacing.

10, lead to pin 2/3/4/5/6/7/8/9/10/11/12/13;

11, Lead to ESP8266 GPIO 0/2/4/5/9/10/12/13/14/15/16/ADC/EN/UART TX/UART RX;

12, RESET-reset;
