Any idea about the sensors? The heart rate sensor is obvious, and I'm sure there are accelerators. I think the white topped part near the TI battery charger is an altimeter. Anything else on there that anyone recognizes?

Chris Arney - 回复

Hi Chris,

Yes it's a MS5805-02BA01 pressure sensor.

I've been trying to repair a Fitbit charge and the device had a dry joint. Sadly I was unable to repair it. Bin job :(

Russell Gibb -

Could you show photos of the area where the Heart Rate Sensor is located. It is Seen clearly in Step5 - first picture. Is it a custom sensor or does it use a 3rd party sensor

Fitbit Wearer - 回复

Is it possible to replace the glass that goes over the screen?

Tim - 回复

@Tim: yes, I would like to know the same thing? Is it possible to replace a cracked screen and if so, how much is the part?
