Fitness Tracker/Wearable Solution

There are many types of fitness or activity trackers available on the market that can monitor your heart rate, your sleep patterns or your performance in a variety of sports activities. Our solution showcases how a 32-bit microcontroller (MCU) can be used to create a variety of products for the healthcare and wearables markets.

The interactive block diagram below illustrates how our products can be integrated to create a fitness tracker/wearable application. Click on each product to learn more about it.

This fitness tracker demo displays heart rate readings measured in beats per minute (bpm) on a low-power E ink display, and optionally posts this data to the Microchip Bluetooth® Data mobile application for Android™ via Bluetooth Low Energy (for SAM E51-based demo only). Here’s a quick overview of how it works:

The host SAM D21 or SAM E51 MCU communicates with a MikroElektronika Heart Rate 9 click board over the I²C interface and with a MikroElektronika eINK click over the SPI interface
The Heart Rate 9 click board provides accurate heart rate readings when you place an index finger on top of the sensor
The eINK click bundle features a low-power display that shows the heart rate and retains data even after the device is disconnected from a power source
The BM71 Bluetooth module is used to send the heart rate data over Bluetooth Low Energy (for SAM E51-based demo only)

Our Ultra-Low-Power Connected Demo Reference Design (ATULPC-DEMO) is also available for creating similar applications.
