1. Introduction
The Thunderboard EFM32GG12 (OPN: SLTB009A) is an excellent starting point to get familiar with the EFM32GG12 Giant Gecko
Microcontrollers. The Thunderboard contains an EFM32 MCU together with an on-board SEGGER J-Link debugger for easy program-
ming and debugging through the USB Micro-B debug connector. The debugger also provides a USB virtual COM port for serial connec-
tion to the target application.
Most of the EFM32GG12 I/Os are routed to breakout pads on the sides of the board making it easy to expand on the board features
and evaluate the EFM32GG12 Giant Gecko's features with custom hardware.
