UG279: EFR32BG13 Blue Gecko Bluetooth
Starter Kit User's Guide

A Silicon Labs Wireless Starter Kit for the EFR32BG13 Blue
Gecko is an excellent starting point to get familiar with the device,
and it provides all necessary tools for developing a Silicon Labs
wireless application.

The Wireless Starter Kit Mainboard contains sensors and peripherals enabling easy
demonstration of some of the EFR32™'s many capabilities. An on-board J-Link debug-
ger allows debugging of the attached radio board as well as providing a debug connec-
tion for external hardware.

A plug-in Radio Board contains the reference design for the EFR32 itself, including the
RF section and device-specific hardware.
