Are Ionic and Charge 3 the same inside?

[ChrisRhyss]

Quick question, who's best place at Fitbit to let me know if Fitbit Ionic and Fitbit Charge 3 use the same sensors and PCBA?

A warm welcome to the Community @ChrisRhyss. I'll be happy to clarify your question. 

I was reviewing the Product Manual for each one and this is the information I found: 

Charge 3: 

• A MEMS 3-axis accelerometer, which tracks motion patterns
• An altimeter, which tracks altitude changes
• An optical heart-rate tracker 

Ionic: 

• A MEMS 3-axis accelerometer, which tracks motion patterns
• An altimeter, which tracks altitude changes
  A GPS receiver with GLONASS, which tracks your location during a workout
• An optical heart-rate tracker
• An ambient light sensor 

Let me know if you have any other questions. I'll be around.

Fantatsic, would I be correct in assuming all the higher end Fitbits have the same sensors and PCBAs?
