4 Power supply
4.1 USB
4.2 Battery
2010-04-09 - REVISION
The EFM32-G8XX-STK can get its power from the standard USB mini port. The MCU voltage will be
3.15 volts when USB is connected.
There is a socket for a 20mm coin cell battery, which can be used to power the kit. When the USB is
disconnected and the battery connect switch is turned on, the EFM and its peripherals is powered by
the battery. The VMCU voltage is 2.85 or lower when powered by the battery, depending on the battery
voltage. There is a 0.15V drop down from the battery voltage. The board controller/AEM is not powered
by the battery, so the BSP software support library cannot be used on battery power.
