Rafael,
There are three devices on the DE i2cbb bus:
1 - The Si5351
2 - The RTC
3 - The SWR/PWR meter (if added)
I believe that the v2 is the same.? I do not have one to verify (I have found discrepancies on the DE schematics, so I do not trust the v2 schematics without a v2 for reference).
I am not sure that it is worth the effort to remove the i2cbb bus.? To have the RTC on the system, adding a third bus may be the easiest.
Again, thank you for the information.
