Pulse 3+ is the newest version of our popular Pulse+ board now with an added QWIIC-connector for full compatibility with the QWIIC Ecosystem.

Maxim's MAX30102 is a great new product that combines everything required for a pulse oximeter (including the LEDs and Photodiode !!) on a single tiny chip.

This board is directly compatible with the QWIIC connector standard from Sparkfun. This means easy plug-and-play usage with all QWIIC-compatible shields and boards.

Measuring 14 mm wide and 28 mm long, this board is easily wearable on the finger to measure the pulse of blood. We even provide a Velcro strap to hold it.

Important Note: This device is only meant to be used for Research purposes and is NOT to be used as a medical device. This product is not FDA, CE or FCC approved for consumer use. 


  • Integrates a complete pulse oximeter including the optics. No need for a separate probe. 
  • 880 nm Infrared and 660 nm Red LEDs
  • Improved motion artifact removal for better SNR
  • Easy-to-use I2C interface to connect to any host microcontroller
  • Arduino library available
