Heart rate/oximetry board hosts Maxim biometric IC – in distribution

June 16, 2017 // By Graham Prophet
Distributor Mouser Electronic has the Heart Rate 4 click board from MikroElektronika.

One of the latest health-focused click board s from MikroElektronika, the Heart Rate 4 board measures the oxygen saturation in a person’s blood through pulse oximetry. It incorporates the Maxim MAX30101 pulse oximeter and heart-rate sensor. The tiny, ultra-low-power MAX30101 includes internal LEDs and photodetectors with ambient light rejection and a programmable sample rate and LED current. The MAX30101 also offers a proximity function to save power and reduce visible light emission when the device is away from skin contact.


The heart rate 4 click board can run on either 3.3V or 5V power supplies and communicates with the target microcontroller over an I 2C interface, with additional functionality provided by INT pin on the mikroBUS line. The board is compatible with a variety of development platforms and shields, including MikroElektronika Clicker 2 development boards and Microchip Curiosity development boards.
