Confused about NoteCarrier XS schematics

Hardware

We are thinking to make a variant of our RAK13102 NoteCard Carrier that supports the StarNote.
But I am confused when looking into the schematics for the NoteCarrier XS.
On sheet two it says the NoteCard slot is using I2C to talk to the StarNote slot:

But when looking at the StarNote Connector on sheet 6, there is no I2C, only a serial connection.

What is the required connection between the NoteCard slot and the StarNote slot?

Hey @bernd that’s a typo on the Block diagram. comms between the Notecard and Starnote are serial only, so the schematic is correct.
