SZDOIT ESP8266 Development Board Web Sever Serial WiFi Expansion Board Transparent Transmission/MQTT/HTTP Firmware For Arduino

Option Description:

• General purpose means that the development board is transparent transmission firmware
• MQTT refers to the development board is MQTT firmware
• HTTP means the development board is HTTP firmware

Features:

• The transparent transmission firmware is through the web configuration parameters, and the serial port data can be transparently transmitted to the set address;
• MQTT firmware is through the at and web configuration parameters, the serial port data can be transparently transmitted to the set address, support mqtt;
• The http firmware sends the serial port data to the set address through the http request through the serial port command;

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 board such as Arduino Uno and Mega2560. The Arduino and UNO are connected with a voltage conversion chip, making 3.3V and 5V compatible.
3. The serial port is controlled by a dual-dial 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 require any configuration;
5. Configure WiFi parameters and serial port parameters based on Web Server;
6. Can be used as a stand-alone ESP8266 development board, download official AT command firmware, NodeMCU open source firmware, etc.
7. Can be used as a stand-alone Arduino Uno expansion board with all pins.
