EMW3162 WIFI Shield for Arduino/Nucleo (Waveshare) 

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.

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

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
