EFM32 Wonder Gecko Starter Kit

Energy Micro expands its MCU portfolio to combat energy consumption

Energy Micro's EFM32 Wonder Gecko Starter KitThe most energy-friendly ARM® Cortex™-M4 microcontrollers from Energy Micro, EFM32 Wonder Geckos, are available with new features like floating point unit (FPU), digital signal processing instructions (DSP), and eLL technology. Embedded applications will be able to process data more energy efficiently than ever, making battery operated applications last longer.

All starter kits from Energy Micro includes an on-board debugger, so everything you need to get started is included when you get your kit! Just plug it into your computer to start programming.

EFM32WG-STK3800 includes the ARM Cortex-M4 with FPU at 48 MHz, on-board J-Link debugger from SEGGER, USB cables, capacitive, inductive and resistive sensors, touch buttons, LCD, free energy profiler and debugger software, IDE's and documentation to form your own MCU lab.


  • Unique and autonomous peripherals that ensure energy efficient and sub μA operation in sleep modes
  • Optimized Current vs. Temperature curve - With extreme low leakage technology, the sleep current curve stays flat throughout the whole operation range, from -40°C to 85°C
  • The 32-bit EFM32 Wonder Gecko gives you the energy efficiency benefits of Floating Point Unit and Digital Signal Processing
