Web Sever Configure Mode :
and then you can find the WiFi signal from Arduino shield.
Features
WiFi module is built on ESP-
Shield is pin-
Dual DIP switches is used for serial ports so that this module shield can be used alone as an Arduino Uno expansion board, and also be used as ESP8266 development board;
Serial data is transported to WiFi device transparently, and vice versa. Arduino program does not need any configuration;
WebServer 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;
