I've bought a bunch of these and they all worked. No duds. The form factor is not ideal because the solder bumps stick up as high or higher than the sensor, so your finger touches them. It doesn't affect the function but it makes it a little harder to integrate into a case or project enclosure in a way that looks finished rather than prototype. I use 1" shrink wrap tubing with a small hole cut out for the sensor to cover up the solder pads and surface components on the finished device so it looks better. The seeed max30102 library works fine with these in arduino ide. I've used both 3.3v and 5v to power these and both work fine.

The sensor itself works OK, in that the raw heartrate signal looks reasonably useful at first glance. However I would say the calculated BPM and SPO2 values from the Sparkfun MAX3010x library for Arduino are rather underwhelming, so far as consistency and accuracy. I think this might look better with some more software effort, but that remains to be seen. If there's any motion or change in pressure of the sensor against the skin, that swamps the signal.I provided +5V in to the board; it has its own 3.3V and 1.8V regulators for the chip. You need to either provide your own I2C pullup resistors offboard, or solder-bridge 2 out of the 3 the tiny pads on the back to select a 3.3V or 1.8V level pullup for the I2C signals SDA, SCL.

Good breakout board for quick prototyping, you can add a strap directly to the PCB slots to attach it to your wrist.

I haven’t tried the sensor yet, however, I noticed there was one sensor missing. It should’ve been 2 sensor, I only received one.

Heart rate sensors work as expected.Easy to solder and give reliable signals.

These actually worked. The other brand I bought did not.
