ProtoCentral MAX30003 Single-lead ECG Breakout Board

This product is now also available on ProtoCentral USA. If you’re shipping address in within the United States, get faster and free shipping from the USA.

Update: This is the new version of the board, it’s black and now got a 1.8V regulator for low voltage operation.

MAX30003 is a single-lead ECG monitoring IC which has built-in R-R detection and several other features that make it perfect for a wearable single-lead ECG application.

Several new features on this chip make it ideal for wearable applications. First is the low power consumption – just 85 uW of power and can work from 1.1 V onwards ! Also of interest is the fact that it can work with only two chest electrodes without the need for a third right-leg drive (DRL) electrode.

The best feature of this chip though is the built-in R-R detection algorithm which can measure the time between successive peaks of the QRS complex of the ECG. This means that heart-computation comes right out of the box without any microcontroller-side code requirement. Heart-rate computation just got a lot easier !!

Note: This is a not a medical certified device nor is it intended to be used as one. While this product has the potential to work as a full-fledged patient monitor, careful calibration has to be performed and safety precautions need to be taken. We recommend usage only with a battery power source or an isolated source.
