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
  • Weight: 0.025 kg

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
