讯享网The MAX30102 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 MAX30102 provides a complete system solution to ease the design-in process for mobile and wearable devices.</p> 

The MAX30102 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.</p>

讯享网评估板MAX30102 EVK</p> 

The MAX30102 evaluation kit （EV kit） provides a provendesign to evaluate the MAX30102 integrated pulse-oximetryand heart-rate monitor integrated circuit （IC）。 The EV kitconsist of two boards. USBOSMB is the mother boardand MAX30102DBEVKIT is the daughter board thatincludes the MAX30102 and an accelerometer. The EVkit is powered using the USB supply to generate +1.8Vfor the sensor and +4.5V for the internal LEDs of theMAX30102， and +3.3V for the accelerometer.The EV kit comes with a MAX30102EFD+ installed in a14-pin OESIP package.</p>
