Si118x Biometric Sensor Evaluation Kit
The Si118x-KIT provides a convenient way of evaluating the Si118x Heart Rate Sensors. The wrist board connects via a flexible cable to an EXP expander board. This EXP expander board can be connected to several Silicon Labs MCU and Wireless SOC Starter Kits (for example the MIghty Gecko Starter Kit and Pearl Gecko STK), to allow you to develop your end applications.
