Product Details

The MAX30101 is an integrated pulse oximetry and heart-rate monitor module. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The MAX30101 provides a complete system solution to ease the design-in process for mobile and wearable devices.

The MAX30101 operates on a single 1.8V power supply and a separate 5.0V power supply for the internal LEDs. Communication is through a standard I²C-compatible interface. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all times.

View Detailed Evaluation Kit Information

The MAX30101 evaluation kit (EV kit) provides a proven design to evaluate the MAX30101 integrated pulse-oximetry and heart-rate monitor integrated circuit (IC). The EV kit consist of two boards. USBOSMB is the mother board and MAX30101DBEVKIT is the daughter board that includes the MAX30101 and an accelerometer. The EV kit is powered using the USB supply to generate +1.8V for the sensor and +4.5V for the internal LEDs of the MAX30101, and +3.3V for the accelerometer.

The EV kit comes with a MAX30101EFD+ installed in a 14-pin OESIP package.

MAX30101WING

View Detailed Evaluation Kit Information

The MAX30101WING board is a rapid development board designed to quickly develop application firmware for the MAX30101 pulse oximetry sensor. The MAX30101WING contains the MAX14750A power management IC (PMIC) that supplies a +1.8V power rail (1V8) to the MAX30101 along with a programmable +2.5V to +5V rail (VLED) to drive the MAX30101 internal LEDs. The board is compatible with +1.8V and +3.3V logic (VIO), selectable through jumper JP1. The ZIF Flat Flexible Cable Connector allows integration of the MAX30205EVSYS, which features the MAX30205 silicon-based human body temperature sensor. The board seamlessly integrates with the MAX32630FTHR to enable rapid prototyping and development.

Maxim Integrated brings the convenience of remote health monitoring to your fingertips. The modular architecture allows for a variety of systems to be assembled quickly and easily within a couple of minutes. The system flexibility stems from the FeatherWing^® form factor that provides a plug-and-play interface by adding or removing desired sensors, enabling or disabling a particular sensor, and the frequency data transmission to an online dashboard. The system is built on a Maxim Integrated low-power microcontroller to ensure minimum power consumption for designs on the go.
