Not working
It died on first try, I powered it using an esp32, connected it to the 3v3 and it just died

MAX30102 Sensor
It works "OK" on 3.3V and based others comments I wouldn't try 5v. However I marked it down because of this: 1. Heart actually tracks pretty good with a store-bought unit and I included a TFT display to show HR over time as I moved about. 2. O2 shows as 100% continuously and it should be 96% based on the store-bought unit. 3. Ambient temperature is reasonably accurate but body temp is a few degrees below my body temp. Maybe skin resistance??? I have not looked to see if there is a way to calibrate for O2 readings. Check out Random Nerd Tutorials online for a good tutorial on this sensor.

Faulty
Dead on arrival sadly

Smoked It
It worked for a while using a 3.3V power supply, but when I tried 5V, it was blown out.

Does not work
Bought two of these, none of them, the wiring was fine. I soldered them very carefully, and they still won’t work. They just heat up.

Dead on arrival -- LED does not light
I did not attempt to return the device, because I was delayed 3 months by storm ripping the roof off of my cousin's house.

Product Description and Images Are Confusing
I ordered this and received the MAX30100. I was fully expecting the MAX30102 as stated in the product description. I will probably return this item. Also, packaging was open on the heat sealed end and item dropped out without tearing open the package.

Dead board
Item is not functional. Returned it. Wasted my time.
