Package include:
1 x ESP8266 Web Server Port WiFi Shield Expansion Board ESP-13 for Arduino UNO Mega 2560
1 x Arduino UNO R3 Board with USB cable

• WiFi using industrial-grade chips ESP8266, modules for the ESP-13 with metal shield, anti-jamming
• Standard pin-compatible Arduino Uno, Mega2560 and other control board
• Serial port DIP switch with dual control, so the expansion board can be used alone as an Arduino Uno
• Based on WiFi Web Server configuration parameters and serial port parameters.
• Can be used as an independent ESP8266 development board, download the official AT commands firmware,
