Abstract

 

The  document  describes  how  to  set  up  and  use  the  EVK-NORA-W101  and  EVK-NORA-W106 
evaluation kits for prototyping NORA-W10 open CPU, multiradio modules. To obtain the different 
options for debugging and the development capabilities included in the evaluation board see NORA-
W10 system integration manual
