What does the "Other-half" Communication Bus look like ??
Is there any pic of it on the Interwebs ?

If it has to satisfactorily quench the dreams of Jolla fans, I suppose it has to be one hell of a communication bus, with sufficient bandwidth!
What comes to my mind is some type of USB 3.0???!!

If it is some proprietary bus, I think there would be a learning & adaptation curve!
Does the Sailfish OS documentation, talk anything about the bus ??

Aah its one of the universal 3 pins and 2 pins sockets (the ones in swich boards) :)
and a hawells mainswitch for the power button purpose:)

extra info for the power butt given so you dont make another post:D

My bet for bus specification is Utopia-2:

I thought it was NFC driven, isnt it?

We have to wait untill we will get more info from Jolla

If the other-half can support a camera/CCD chip, then should it not have enough bandwidth to transfer the umpteen RAW megapixels to the host, in under a second ?
At 424 kbit/s NFC, (https://en.wikipedia.org/wiki/Near_field_communication#Essential_specifications) a 8 megapixel CCD's 24-bit RAW image (~23MB) would take a little over 7 minutes !! to reach the host, unless the image compression electronics are already there in the other-half itself!!

It was revealed at the Akademy that the other half on the newer prototypes has power in/out and data in/put. They didn't indicate the type of connectivity but it appears to be much more than just NFC that was shown on Jolla Love Day.

Who says there is a physical connector? I doubt it has. Its overhyped. My guess is that it only is NFC enabled backcover chaning color of backcover etc.

I take everything else as a bonus...

LOL! first of if they ever release a camera backcover, wish I doubt, they could use BT.

prototype it does not mean it actually will be the final one. So don't give hopes on something that may not happen... You know this is TMO saying anything here and people take it for granted its final.

Looks like it might be I²C as quoted on http://www.jolla.com/your-jolla/
Extension interfaces for wireless NFC, power in/out and I2C data connectivity (http://www.i2c-bus.org/).
