BIOMETRIC-EXP-EVB Silicon Labs
Biometric-EXP EVB BIOMETRIC-EXP Evaluation Board USERS GUIDE 1. Introduction The Silicon Labs Biometric-EXP Evaluation Board is a hardware plugin card for EFM32 Starter Kits (STKs). 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. Figure 1.

Key Features Si7013 Humidity and Temperature Sensor Si1146 Proximity/UV/Ambient Light Sensor capable of monitoring Pulse Rate and SpO2 6-pin ribbon cable connector for attaching a postage stamp board 20-pin expansion header Battery operated with low power optimizations for long battery life Demonstration software source code available USB debug mode allowing HRM and SpO2 samples to be transferred to a PC Windows GUI to visualize pulse signals and to record samples from USB debug mode Easy use through Simplicity Studio 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.

Loading the Demo Onto the Gecko Starter Kit The following steps will load the demo firmware onto the Gecko STK. This process requires Simplicity Studio which is available for download at www.silabs.com/simplicity-studio. 1. Use a USB mini type cable to connect the J-Link debug interface on the Gecko STK to the PC and set the 3-position Power Source Select switch to DBG (right-most position). 2. Launch Simplicity Studio.
