This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

Maxim Integrated Reference Design

Maxim Integrated’s MAXREFDES220# is a reference design for prototyping finger-based heart rate and blood oxygen saturation monitors using the MAX30101 and MAX32664. 

The MAX30101 is a heart rate monitor and pulse oximeter module in a tiny optical package and offers ultra-low power consumption for use in mobile devices.

The MAX32664 is an ultra-low-power biometric sensor hub with Maxim-licensed firmware that includes the algorithms for calculating heart rate and blood oxygen saturation.  The board also includes a 3-axis accelerometer to compensate for motion artifacts in the measurement.

The board plugs into the included MAX32620 development board to process the data and transmit it for review on the Maxim DeviceStudio software.
