The heart rate monitor unit also contains an accelerometer chip to measure runners vertical oscillation and estimate foot strike cadence - that chip could be the mystery chip that they couldn't identify.
The same heart rate monitor can be used, and may be bundled, with several Garmin fitness products. I think this should be 2 videos: one for the FR 220, and another for the HRM
At 6:27, he says the power supply "is the coin cell on the watch." The coin cell from the HRM is shown. Near the end, the battery for the watch is shown to be a different battery, and it's not a coin cell.
Very interesting - thanks! Would've been nice to see the watch's antenna though. And a shame about the annoying music though. Can't help with the level-shifters though!
The 4bit level shifters that puzzled the presenters may be there to prevent power drain through the data busses when portions of the device are powered down when not tracking fitness activity?
can you tell me what the model number is on that battery is? You start showing it at about 8:00 min. Does anyone know the where I can get a new battery for this watch?
The watch battery is not user-replaceable. When the watch battery will no longer hold a charge, you should either replace the watch or send it to a qualified repair service. Note the makers of this video had to break the watch case to show the insides.
Wow. Such an informative video! The hosts make it even better

For some reason, hearing him say "... sensors up the ying yang" cracked me up! I think his co-host was trying not to laugh at that point too.

It is a CR2032 battery, and is common. Even my grocery store sells it. static.garmin.com/pumac/HRM_Soft_Strap_ML_Web.pdf
@@jamesfunk7614 It isn't 2032 battery, that one is going into chest strap, in watch is battery with part number 361-00072-00 3,7V 150mAh
@@tihidugi You're right. I was thinking of the chest strap battery, at the beginning of the video, but he asked about the the watch battery.

If you decide to toss the watch, please use an electronics waste service. Please do not put it in the regular trash.
Thumbs up.?
