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
