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.
