Functional Overview 

The  processing  core  of  the  emVIEW-7/RPI3  is  an  unmodified  Raspberry  PI  3  B  board.  A  Janz  Tec 
specific  add-on  board  implements  the  specific  features.  Refer  to  figure  1  for  the  block  diagram.  The 
display is the unmodified Raspberry 

7” display with integrated touch screen.
