    • This is primarily a video teardown, but intrepid iFixit community members have also submitted their own analyses. One reader in particular spent hours attempting to reverse engineer the Oura Ring 2 through the video, datasheets, and X-rays, and shared the following:

    • The two IR LED drivers should be the same type, one for each IR LED.

    • There's likely an operational amplifier for signal conditioning for the photo diode before the signal is sent to the microcontroller. (This is commonly done with these type of photo diode based health meters.)

    • If this is not a microcontroller, it could be a temperature sensor (not a thermistor).

    • A wireless charging IC, predicted based on its surrounding components and location.

    • And finally, a battery fuel gauge IC for probably determining battery health.

    • Based on all this, the second image shows the predicted block diagram.

Wow, I didn’t even know smart rings existed. I also think that it’d be much easier to service if the titanium shell came off in two halves so nothing would have to be bent to service the electronics.

Is it possible for you to share SMD Markings on all the devices?
