SLSTK3400A - 

The SLSTK3400A is an EFM32™ Low Energy USB Interface Happy Gecko Starter Kit, provides an excellent tool to get familiar with the EFM32™ USB-enabled Happy Gecko 32-bit microcontrollers (MCUs), the industry's most energy-friendly MCU based on the ARM® Cortex®-M0+ processor. Supported by Simplicity Studio, the starter kit contains sensors and peripherals, touch-buttons, LEDs, Si7021 Digital Relative Humidity and Temperature Sensor, memory LCD and simplicity header, demonstrating some of the MCU's many capabilities and can serve as a starting point for application development. The SLSTK3400A includes AEM (Advanced Energy Monitoring) and the Energy Profiler capabilities allowing real-time energy profiling of your application. This kit has two AEM-channels, one for measuring the current consumption in self-powered mode and one for monitoring the VBUS-current when the chip is USB-powered.
