ESP8266 Web Sever Serial WiFi Shield Board Module W ESP-13 For UNO R3
1, WiFi uses industrial chip ESP8266, module ESP-13 with metal shield, strong anti-interference capability;
2. Standard pins are compatible with main control boards such as Uno and Mega2560. Voltage conversion chips are used in UNO connection to make 3.3V and 5V compatible.
3. The serial port is controlled by a two-way dial switch, so that the expansion board can be used either as an Uno expansion board alone 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 Web Server.
6. It can be used as an independent ESP8266 development board, downloading official AT instructions firmware, NodeMCU open source firmware, etc.
7, can be used as an independent Uno expansion board, pin all lead.
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, serial port baud rate support: 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;
13, KEY button reconfiguration function;
14, two bit dialing switch to achieve for Arduino and ESP8266 serial expansion switch;
15, WiFi working current: continuous transmission: 70mA (200mA MAX), standby: <200uA;
16, wireless transmission rate: 110-460800bps;
17, working temperature:-40C~+125C
18, module weight: About 20g
