The EFM32GG-STK3700 is an excellent starting point to get familiar with the EFM32™ Giant 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 Giant 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.

EFM32 Giant Gecko ARM Cortex-M3 based 32-bit microcontrollers (MCUs) provide flash memory configurations up to 1024 kB, 128 kB of RAM and CPU speeds up to 48 MHz, making them ideal for energy sensitive applications with high memory and connectivity requirements. The Giant Gecko MCUs are available in packages down to 7x7 mm, as well as full wafer options, and feature autonomous, low energy peripherals, including AES encryption, pulse counter, low energy UARTs, a low energy sensor interface and on-chip operational amplifiers.

The USB connectivity option is USB 2.0 compliant at full speed (12 Mbps), integrating 2 kB endpoint buffers and handling up to 14 endpoints. The Giant Gecko MCUs provide support for USB host, device and on-the-go configurations, as well as bootloader over USB.

Applications: Gas metering, Energy metering, Smart metering, Alarm and security systems, Health and fitness applications, Industrial and home automation.
