Power Management – Debug Test Setup
●
Ideally, use 2 separate power supplies. This
allows you to monitor current to both USB and
battery at the same time.
●
The USB power supply will always be 5.0V
with a 3A current limit.
●
The Battery power supply will always be 4.0V
with a 3A current limit.
●
For USB power supply, there are 2 options:
○
Use a Warthog board to supply USB
power externally
○
Modify a USB cable. Cut open the
cable, cut the red wire, and connect it to
the external power supply.
