A tool for optical Bio-Sensing algorith development –

Stock Availability Date – 9/22/2014

The AFE4403 Watch EVM uses Texas Instruments’ (TI) fully-integrated analog front-end, MSP430 and CC2541 for a robust PPG data acquisition at the wrist. The modular design comes with two different sensors and allows the user to design in and swap out sensors easily.

Captured PPG data may be transmitted via BLE or stored in the flash memory. PPG data stored in the flash memory can be downloaded to a PC using an USB interface for offline algorithm development. .

Key Features:

  • Fully-integrated analog front-end for pulse oximeter applications
  • Based on MSP430F5528 (more details found at http://www.ti.com/product/msp430f5528)
  • BLE Connectivity
  • 9-axis Motion Tracking device that includes a three-axis MEMS accelerometer
  • 24 pin connector for sensor board daughter cards
  • 256 Mbit Flash memory
