Arduino WIFI Shield EMW3162

Overview

EMW3162 WIFI Shield consists of a base board and a WiFi module 

EMW3162. It allows you to connect your Arduino/Nucleo board with 

the Internet. Thanks to the EMW3162 WIFI Shield, WiFi communication

will become easy for devices that feature Arduino connectivity.

What's on Board

1. Arduino interface : for connecting with Arduino boards and/or Arduino shields

2. EMW3162 connector : for connecting the WiFi module EMW3162

3. EMW3162 extend pin headers : access to the common used pins of EMW3162

4. SWD interface : for programming and debugging

5. USB TO UART interface : for UART debugging and/or firmware updating

6. FT230XS : onboard USB to UART converter

7. RT9193-33 : onboard 3.3V regulator

8. Fuse : 500mA fast self-recovery fuse

9. BOOT switch

• turn to H, the BOOT pin will be connected to 3.3V

• turn to L, the BOOT pin will be connected to GND

10. STATUS switch

• turn to H, the STATUS pin will be connected to 3.3V

• turn to L, the STATUS pin will be connected to GND

11. WiFi indicator : LEDs for indicating the WiFi communication status

12. WPS key

• press the key, the EMW3162 will start WPS matching

• press the key and hold it for 5 seconds, the EMW3162 will recover to 

       factory setting EASYLINK key

press the key, the EMW3162 will start EasyLink matching

13. RESET key

14. Power indicator

15. WiFi serial port configuration jumpers

• connect the WFRX to FTTX, WFTX to FTRX respectively, you can

       communicate with the EMW3162 through USB TO UART interface.

• connect the WFRX to TX, WFTX to RX respectively, you can

       communicate with the EMW3162 through Arduino interface.

Features

The WiFi module EMW3162 :

• As easy to use as an serial module with the provided serial transparent 

       transmission firmware

• High stability, hardly goes down

• Ultra low power consumption, online standby 7mA only

• Optional antenna, onboard antenna OR external antenna via IPEX

The base board :

• Compatible with Arduino interface, use UART only

• Works as an Arduino WiFi Shield, connects to Arduino boards like : UNO, 

       Leonardo, Nucleo, Xnucleo, etc.

• Works as an Arduino WiFi board, allows connecting with Arduino shields

• Onboard USB to UART converter FT230XS, for UART debugging and/or 

       firmware updating

• Onboard WiFi TX/RX LEDs, indicating the WiFi communication status

• Supports EasyLink fast matching (instant networking by pushing the SSID 

       and password of the wireless router via smart phone APP)

• Supports one-key recovery to factory setting (no need to flash the firmware 

      for configuration errors)

• Flexible boot mode configuration

• 500mA fast self-recovery fuse, stable and safe
