Product Details

The MAXM86161EVSYS# evaluation system (EV sys-tem) allows for the quick evaluation of the MAXM86161 integrated optical module for applications at various sites on the body, particularly in-ear and mobile applications. The MAXM86161 device communicates using a standard I2C-compatible interface to Analog devices on-board MAX32664 Biometric Sensor Hub microcontroller (used for Analog devices algorithm evaluation) or in a pass- through mode for raw data collection. The MAXM86161 device consists of three optical readout channels that can be individually controlled (Green, Red, and IR). The EV system allows for flexible configurations to allow testing of various features of the sensor. Moreover, it helps the user quickly learn how to configure and use the MAXM86161 device.

The primary EV system consists of two circuit board assemblies (MAXSensorBLE_EVKIT and MAXM86161OSBFLEX), one USB-C to USB-A connector cable, and a Lithium Polymer battery. These components are highlighted in Figure 1 below. In addition, two programming circuit boards (MAXM86161_MAX32630_ PRGMR_ASSY, and the MAXREFDES100HDK) and one USB-B Micro-to-USB-A Male USB cable are provided for firmware updates if needed.

The EV system can be powered using a USB-C supply or LiPo Battery and comes with a MAXM86161EFD+ device in a 14-pin OLGA package.

The MAXM86161OSBFLEX Flex-Rigid circuit board has a Analog devices MAX32664 Biometric Sensor Hub microcontroller device installed. This Sensor Hub can be used to implement Analog devices HR/SpO2 Algorithm for evaluation. The MAXM86161 GUI PC application code that allows evaluation of both the MAXM86161EVSYS# and the MAX32664 Sensor Hub is available in the MAXM86161EVSYS# EV System Design Resources tab.
