The MAXREFDES117# reference design is a low power, optical heart-rate module complete with integrated red and IR LEDs, and a power supply. It is designed by Maxim Integrated and manufactured by Seeed Studio.
This tiny board, perfect for wearable projects, may be placed on a finger or earlobe to accurately detect heart rate. This versatile module works with both Arduino and mbed platforms for quick testing, development and system integration. A basic, open-source heart-rate and SpO2 algorithm is included in the example firmware.
The board features 8 sewing tap pads for attachment and quick electrical connection to a development platform.
As with all Maxim reference designs, the BOM, schematics, layout files, and Gerber files are all available from the Design Resources tab.

extremely small and powerful component I haven't tested the SPO2 capabilities (the sample algorithm is very limited), but you can clearly see the heart beat in both signals, red and infrared, even in other places than finger tip. Online documentation is excellent.

Good value Slightly handicapped in the sense that the sensor was not Grove?Shield ready. Needed to buy a soldering kit and some very minor parts to get going. Also, had to brush up my soldering skills that were lying dormant.
