Description: 1, WiFi using industrial-grade chips ESP8266, modules for the ESP-13 with metal shield, anti-jamming;
2. Standard pin-compatible Uno, Mega2560 and other control board, 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 Uno expansion boards, it can also be used as ESP8266 expansion board use;
4, Real serial WiFi, 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 Uno use, pin all leads.
