Hello,
I've noticed that from the base board (at least the beta version in GIT) there is only external connection for 5V (or better to V_UNREG) I2C. Why this decision?
Given tha almost all i2c sensors out there are 3v only won't be better to remove altogether the i2c level translator and put outside the 3.3v I2C?

So much has changed in the hardware, the beta hardware was well over  a year ago now. At that time external I2C was all about MK ESCs hence that choice.

Is there any updated documents available for the hardware?

Thanks.

There will when its done, still a work in progress currently.

Also the EagleTree sensors are 5V

Also the flexi-port on CC (that provides I2C) could be also used as a USART.  It's nice to have a consistent pin-out between boards.
