1. Introduction
The Silicon Labs’ Biometric-EXP Evaluation Board is a hardware plugin card for EFM32™ Starter Kits (STK’s). The
Biometric-EXP is intended to demonstrate and evaluate the biometric applications of Silicon Labs Si7013 Humidity
and Temperature Sensor and the Si1146 Proximity/UV/Ambient Light Sensor which is capable of monitoring pulse
rate and oxygen saturation (SpO2). A Biometric-EXP Software Demo is available to download to an EFM32
Wonder Gecko STK through Simplicity Studio. The software is capable of displaying humidity, temperature, UV,
pulse rate, and SpO2 readings on the Wonder Gecko STK display. In addition to the Silicon Labs sensors, it is also
notable that the Biometric-EXP EVB contains a Silicon Labs’ TS3310 Boost DC-DC Converter.

1.2. Getting Started
The first step to getting started with your new Biometric-EXP-EVB is to download Simplicity Studio from
www.silabs.com/simplicity-studio
.
The simplicity studio software package contains all the tools, drivers, software examples, and documentation
needed to use the Biometric-EXP-EVB.
You will need to connect the Biometric-EXP-EVB to the EFM32WG-STK3800 Wonder Gecko STK or the
EFM32GG-STK3700 Giant Gecko STK. The demo code can be loaded using the USB cable and the J-Link debug
interface.
