Extra details from the Processor PCB.
A Buzzer reference in the PCB.
And a UART serial I/O as well.

General parts view.
The Prime uses five key sets.

The battery is a pretty standard component, available in most retail shops under the Samsung cell phones accessories section, although with a different reference number but as long as the specifications are similar it should be fine.
Specs: Lithium-Ion 3.7V 1500mAh (5.55Wh)
Battery model: 484461AR

Note:
Meanwhile I have tested the Prime with a 3-years old battery from a Samsung Galaxy SIII I9300 and it worked fine.
Samsung Battery Specs: 3.8V Li-Ion 2100mAh (7.98Wh)
Samsung Battery model: EB-L1G6LLU

Reassembling the machine in reverse order was quite easy and took about 15 minutes.
It booted normally as soon as the battery was inserted in the compartment.

Happy 2015 Christmas holidays for all!
I'm signing out and go to the high mountains in the North of my little country, where the chilly wind and negative temperatures during the night keeps you inside home drinking with the family and celebrating the season.
