1. Introduction
The Silicon Laboratories’ 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
Laboratories 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 of note that the Biometric-EXP EVB contains a Silicon Laboratories’ TS3310 Boost
DC-DC Converter.
