The mikromedia+ for STM32 ARM
®
board can be powered in three dierent 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 values must be within 2.5-12V 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.
