Power 

EVK-NORA-W36 can be powered from five sources: 

Source

Table 1: EVK-NORA-W36 power sources 

These  power  sources  are  protected  from  reverse  polarity  by  protection  diodes,  allowing  multiple 
sources to be present simultaneously. 

When powering the EVK from either 

VSHLD

 or the power header, the Li-Ion battery and USB power 

sources  can  be  isolated  by  cutting  jumper  NC3  as  shown  in 

Figure  7

.  This  allows  connecting 

alternative external power sources while still powering the module through J8 or J10, 

VSHLD

 

Figure 7: High-voltage power isolation 

After applying power to one of the sources, slide SW1 to the ON position to power on the EVK.

Reset 

An active-low reset signal 

 

nRESET

 

 is connected to the NORA-W36 module, the Arduino header 

J10, pin 3, and a momentary button switch. Pressing the switch or driving the signal low resets the 
NORA-W36. 

nRESET

 is pulled high internally, so an open-drain source may be used.
