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.

Development

Kit firmware upgrade

Regrettably, the firmware version that was shipped on the first batch of Pearl Gecko boards wasn't mbed-enabled yet. To update your board to a firmware that supports mbed, please follow the guide here.

The following images depicts the default pin-out for this MCU on this kit. Advanced users will note that on this device any function can be routed to any pin.
