INTRODUCTION
EFM32G880F128-STK development board provides easy way for developing and
prototyping with the new EFM32G880F128 energy friendly microcontroller,
produced by Energy Micro AS. The combination of the powerful 32-bit ARM
Cortex-M3, innovative low energy techniques, short wake-up time from energy
saving modes, and a wide selection of peripherals, the EFM32G880F128
microcontroller is well suited for any battery operated application as well as other
systems requiring high performance and low-energy consumption.
EFM32G880F128-STK has DBG port for programming and debugging, UEXT, EXT,
four user buttons, RESET button, buzzer, LCD and some of the GPIOs are on
extension headers where you can connect your additional circuits. All this allows
you to build a diversity of powerful applications to be used in a wide range of
applications.
