MAX86173EVSYS#

MAX86173EVSYS# is a MAX86173 evaluation system (EV Sys) that allows for quick evaluation of the MAX86173 optical AFE for applications at various sites on the body, particularly the wrist. MAX86173 supports both I2C and SPI compatible interfaces. MAX86173 has two optical readout channels that operate simultaneously. The EV Sys allows flexible configurations to optimize measurement signal quality at minimal power consumption. The EV Sys supports file logging and flash logging, allowing users to disconnect from the computer for more convenient data capturing sessions, such as overnight or outdoor running. It consists of two boards. MAXSENSORBLE_ EVKIT_B is main data acquisition-board while MAX86173_OSB_EVKIT_B is sensor daughter board for MAX86173. To enable PPG measurement capabilities, the sensor board contains eight LEDs (OSRAM CT DBLP31.12, green LED, and OSRAM SFH7013, red, green, and IR 3-in-1 LED package) and four discrete photodiodes (Vishay VEMD8080), and an accelerometer.
