The mik for PIC32MX7
®
board can be powered in three different ways: via USB connector using MINI-B USB cable provided with
the board
(CN4)
, via battery connector using Li-Polymer battery
(CN5)
or via screw terminals using laboratory power supply
(CN3)
. After
you plug in the appropriate power supply turn the power switch ON
(SW1)
. The USB connection can provide up to 500mA of current
which is more than enough for the operation of all on-board modules and the microcontroller as well. If you decide to use external power
supply via screw terminals, voltage levels must be within
5-12V DC
range. Power
LED ON (GREEN)
indicates the presence of power
supply. On-board battery charger circuit
MCP73832
enables you to charge the battery over USB connection or via screw terminals.
LED
diode (RED)
indicates when battery is charging. Charging current is ~250mA and charging voltage is 4.2V DC.
