Abstract

 

This  manual  provides  a  functional  overview  combined  with  best-practice  design  guidelines  for 
integrating NORA-W30 series stand-alone, dual-band Wi-Fi and Bluetooth Low Energy modules in 
customer  applications.  It  also  describes  open  CPU  application  development  solutions  using  the 
Realtek SDK. The multi-radio modules are ultra-compact, cost-efficient, and designed in the NORA 
form factor for a wide range of industrial applications. The module series also includes variants with 
or without an internal antenna.
