Yuneec Breeze sensor triple board content?

[Vaklin]

Hi!
I'd like to use this board in one of my projects. As I understood, there is no clear definition of the cable's pinout description. This is not a big problem, when the PCB is in my hands, I'll redraw the schematic.
Another problem for me is that this part is mentioned as a triple sensor. One is GPS, the second is an altimeter, what is the third one? It isn't compass for sure, because compass PCB is available separately for this drone.

Here is the picture:


If someone can read exactly what is typed on the barometric sensor and undefined IC will be good. I'll try to find some datasheets for these.

Any idea for what is the EEPROM will be welcome...

The unknown IC is most likely an MPU-6050. I'll confirm this after two weeks when the parcel with the PCB's comes to me.

I’m taking mine out of the Breeze to have a peek. Will let you know soon.

Thank you!

Let these datasheets stay here for now. As I see, I'm not alone in the interest to prepare something useful from CGO3+ and Steady grip, In the near future I'll have a Steady grip for investigation, and probably, a separate topic with ideas and hardware solutions will be welcomed from the people. Unfortunately, all with ideas are not programmers, but with collective efforts, we will involve some enthusiast programmer in the world of drones.

Here are the voltages I get on the unit:


Open connector:
1) 3.21V
2) 3.22V
3) 0.0V
4) 3.3V
5) 3.3V
6) 0.20V
7) 3.3V
8) 5.0V
9) 0.0V

Plugged into GPS board:
1) 3.18V
2) 3.19V
3) 0.0V
4) 3.0V
5) 3.0V
6) 3.1V
7) 3.3V
8) 5.0V
9) 0.0V

All voltages are relative to frame of the heat sink.
