Note: This version of UNO R3 can not compatible with OS system
Introduction: ESP8266-Based Serial WiFi Shield for is designed and developed by Shenzhen Doctors of Intelligence & Technology (SZDOIT). The shield is designed based on esp8266 by Espress if Systems, pin-compatible with UNO/Mega2560 Development Board.
Features: WiFi module is industrial-grade chips ESP8266, which is ESP-12E with metal shield, strong anti-interference ability
Shield is pin-compatible with Uno, Mega2560 and other control board. A voltage converter chip is used to deal with 3.3V (Esp8266) and 5V ();
Dual DIP switches is used for serial ports so that this module shield can be used alone as an Uno expansion board, and also be used as ESP8266 expansion board;
Serial data is transported to WiFi device transparently, and vice versa. program does not need any configuration;
Web Server is developed to configure WiFi parameters and serial port parameters
The module shield can be used as an independent ESP8266 development board. for instance downloading the official AT commands firmware NodeMCU open source firmware can be used
The module shield also can be used as stand-alone expansion board for Uno.
