Figure 2.2 

Box header for Streaming/Programming.  

The  mother  board  includes  a  box  header 
for programming and streaming the IQS127 
devices  through  Azoteq  configuration  tools 
(CTxxx) to a PC, as well as two jumpers: 

 

W1 

– for measuring current 

 

W2 

– for back-grid selection 

Figure  2.3  shows  the  bottom  view  of  the 
mother  board.  The  daughter  boards  are 
powered  by  two  3V  coin  cell  batteries,  in 
series,  which  is  regulated  on  the  mother 
board to 4.5V. A ground pin and mini USB 
connector  is  also  available  to  connect  and 
review  the  effect  of  introducing  larger 
ground references.
