It works
Working as expected, I’m using a ESP32-S3 module

Works
I got this to work on the first try! It picks up my pulse pretty well and aligns with my ecg’s rate. The first couple of seconds of readings can be way off, but it settles down.

raw signals look OK, will need some software though
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.

Works great
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.

wrong sensors
For starters, the product is not the same one that they advertise. This is like a cheap knock off version of the original sensors. The sensor did not turn at all. Both sensors didnt turn on. They were faulty and was unable to get them to power on. I’m very disappointed in my purchase and can’t even get a hold of the seller to talk to him about it.

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

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

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