General Description
The MAX86174 evaluation system (EV Sys) provides a platform to evaluate the
functionality and features of the MAX86174A with photoplethysmography (PPG)
measurement capabilities. The EV Sys allows for flexible hardware and software
configurations to help the user quickly learn how to configure and optimize
the MAX86174A for their applications.
The MAX86174A is an ultra-low power PPG analog frontend solution that has dual
optical-readout channels and supports up to 4 LEDs and 2 photodiode inputs.
For more information, refer to the MAX86174A data sheet.
The MAX86174 EV Sys consists of two boards. MAXSENSORBLE_EVKIT_B is the
microcontroller (MCU) board while MAX86174A_OSB_EVKIT_B is the sensor board
containing the MAX86174A. To enable PPG measurement capabilities, the sensor
board contains 3 LEDs (red, green, and IR in a single package: OSRAM SFH7016),
three discrete photodiodes (Vishay VEMD8080), and an accelerometer. The EV Sys
is powered through the included LiPo Battery. The EV Sys communicates with
MAX86174GUI (should be installed in the user’s system) using Bluetooth built
into Windows (Win BLE). The EV Sys contains the latest firmware but comes with
the programming circuit board MAXDAP-TYPE-C in case a firmware change is
needed.
