...the world's most energy friendly microcontrollers

The EFM32-G8XX-STK can get its power from the standard USB mini port. The MCU voltage will be volts when USB is connected.

Battery

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 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.
5 Reset infrastructure
...the world's most energy friendly microcontrollers

The primary user reset for the MCU is the reset button on the MCU board. This will only reset the MCU. The MCU can also be reset by debuggers.

Board controller

The board controller can only be reset by pulling and reinserting the USB cable.
6 Peripherals
...the world's most energy friendly microcontrollers

The starter kit has a set of peripherals that showcase some of the features of the EFM32G.

Be aware that most EFM I/O routed to peripherals are also routed to the breakout pads. This must be taken into consideration when using the breakout pads for your application.

Pushbuttons

The kit has two user pushbuttons marked PB0 and PB1. They are connected to the EFM, and are debounced by RC filters with a time constant of 1ms.
