Description:

1. WiFi using industrial-grade chips ESP8266, modules for the ESP-13 with metal shield, anti-jamming;

2. Standard pin-compatible Arduino Uno, Mega2560 and other control board, Arduino UNO connection with the use of a voltage converter chip, so 3.3V and 5V are compatible;

3. Serial port DIP switch with dual control, so the expansion board can be used alone as an Arduino Uno expansion boards, it can also be used as ESP8266 expansion board use;

4. Real serial WiFi, Arduino program without any configuration

5. Based on WiFi Web Server configuration parameters and serial port parameters;

6. Can be used as an independent ESP8266 development board, download the official AT commands firmware, NodeMCU open source firmware;

7. can be used as stand-alone expansion board Arduino Uno use, pin all leads.
