Robodo ESP13 Shield Board ESP8266 Web Sever Serial Wi-Fi Expansion Board Electronic Components Electronic Hobby Kit

Features:1. WiFi using industrial-grade ESP8266 chips, modules for ESP13 with metal shield, strong anti-interference ability;2. standard pin compatible with the Ar-duin Uno, Me ga2560, such as main control board, a voltage conversion chip is used to connect with the Ar-duin Uno, 3.3V and 5V compatible;3. a serial port using dual dial the code switch to control, makes the extension board can separate as Ar-duin Uno extended board is used, can also be used as ESP8266 extension plate;4. Real serial WiFi, the Ar-duin program without any configuration;5. WiFi based on the Web Server configuration parameters and serial port;6. Can be used as an independent ESP8266 development board, download the official firmware the AT command, Node MCU open-source firmware, etc;7. Can be used as an independent Ar-duin Uno expansion board, pins all leads. Specifications:1. Support wireless 802.11 b/g/n standard;2. Support the STA/AP two working mode;3. Built-in TCP/IP protocol stack, you can configure a socket;4. Support the standard TCP/UDP Server and Client;5. A serial port baud rate support: 1200/2400/4800/9600/4800/9600/57600/74800/115200 BPS.6. A serial port data bits: 5/6/7/8;7. Serial ports, parity: no;8. Serial ports, stop bit: 1/2;9. Standard Ar-duin UNO, Me ga pin spacing;10. Which leads to the Ar-duin Pin 2/3/4/5/6/7/8/9/10/11/12/13;11. Which leads to the ESP8266 GPIO 0/2/4/5 9/10/12/13/14/15/16 / ADC/EN/UART TX/UART RX.12. RESET RESET;13. KEY buttons reuse configuration function;14. Two dial the code switch to realize the Ar-duin and ESP8266 serial port extension switch;15. WiFi working current: continue to send: material 70 ma 200 ma (MAX), standby: < 200 ua;16. Wireless transmission rate: 110-460800 BPS17. Working temperature: - 40 + 12518. Modules weight: about 20 g
