Description

This reference design is for a complete body weight scale end equipment with body composition capability featuring TI signal chain, power, and connectivity components. With TI's AFE4300 weigh scale/body composition AFE, you can accelerate your body weight scale design or quickly add body composition measurement features to your existing platform. This reference design also includes the full BLE connectivity design for easy interface to BLE enabled smartphones, tablets, etc.

Features
  • Features AFE4300 for both bio-impedance body composition measurement as well as weight measurement
  • MSP430F5528 microcontroller for holding calibration data and computing weight, TBW, ECW, and body composition analysis
  • BLE module connection featuring TI's CC2541
  • This design is tested and provides everything you need to complete your design including Schematics, Layout and Gerber files, and BOM.
