TIDA-00301

Miniaturized Optical Heart Rate Reference Design

TIDA-00301

Design files

Overview

This reference design is for a miniaturized Optical Heart Rate Monitor measurement solution (no chest strap!) specifically targeted for wearable and mobile applications. The small form factor module can easily interface to smartphones, tablets, and wearables. With TI's AFE4403 AFE, you can accelerate and simplify your Optical HRM design while still ensuring measurement performance needed for serious Fitness designs.  This design is a smaller form factor than TIDA-00011.

Features
  • Supports optical heart rate measurement 
  • Features AFE4403 and third party optical sensor module for measuring heart rate
  • Targeted for smart phones, tablets, wearables 
  • MSP430F5528 MCU for holding algorithm for each measurement
  • This design is tested and provides everything you need to complete your design including Schematics, Layout, Gerber files, and BOM

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
