The mikromedia+ for PIC32MX7
®
board can be powered in three dierent 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.
