Analog Devices / Maxim Integrated MAXREFDES220 Reference Design
Analog Devices Inc. MAXREFDES220 Reference Design includes everything to prototype finger-based heart rate and blood oxygen saturation level (SpO2) products. The board features the MAX30101 and MAX32664 to provide an integrated hardware and software solution for multiple finger-based applications. The MAX32664 firmware offers digital signal processing to process the data. The reference design also includes a tri-axis accelerometer to compensate for motion artifacts. An ADI MAX32630FTHR is provided to emulate a host system for easy development.
