Product Details

The MAX30003WING is an expansion board designed to help engineers and students alike to rapidly prototype ECG applications for wearables using the MAX30003 biopotential analog front end. The form factor is a small 0.9in by 2.0in dual-row header footprint that is compatible with breadboards and featherboards from Maxim and Adafruit®, as well as additional expansion boards called wings. Two grove connectors and a 6-pin Pmod™ connector are also included for additional connectivity to popular development boards offered by Seeed Studio® and Diligent®.


  • Bio Authentication and ECG-On-Demand Applications
  • Chest Band Heart Rate Monitors for Fitness Applications
  • Single Lead Event Monitors for Arrhythmia Detection
  • Single Lead Wireless Patches for At-Home/In-Hospital Monitoring
