EFM32 Pearl Gecko

Silicon Labs' EFM32™ Pearl Gecko ARM® Cortex®-M4 based 32-bit microcontrollers (MCUs) provide flash memory configurations up to 256 kB, 32 kB of RAM and CPU speeds up to 40 MHz, providing a full DSP instruction set and includes a hardware FPU for faster computation performance.

SLSTK3401A¶

Silicon Labs' SLSTK3401A is an excellent starting point to get familiar with the EFM32™ Pearl Gecko 32-bit microcontrollers. The starter kit contains sensors and peripherals demonstrating some of the MCU's many capabilities and can serve as a starting point for application development. The Pearl Gecko features an on-board SEGGER J-Link debugger and an Advanced Energy Monitoring system, allowing you to program, debug and perform real-time current profiling of your application without using external tools.
