Max30001 EVKIT Summary

The MAX30001 EVKIT SYS-MBED Evaluation System (EV System) is used to evaluates the MAX30001 sensor, which is an ECG (electrocardiogram), biopotential and bioimpedance analog front end solution for wearable applications. The full EV System consists of the MAX32630FTHR Development board (DEV board) and MAX30001 sensor board and the evaluation software. The EvKit features EKG, PACE, RtoR (R-peak timing), Bio-Z, and raw data logging.

The MAX30001 EVKIT SYS-MBED evaluation system is assembled, tested and contains the necessary circuitry and connections to evaluate the MAX30001 sensor.

When evaluated as an EV System, the MAX32630FTHR board provides the necessary logic rails, master clock, SPI, USB-to-Serial interfaces that are needed to evaluate the MAX30001 sensor board. MAX32630FTHR can be used as an independent development platform. Another wiki page for that platform is available here.

Communication with the DEV board is facilitated by Windows 7, Windows 8 and Windows 10 compatible software that provides a simple and intuitive graphical user interface (GUI).
