[Solved] What power source(s) do I need to get my FabScanPi working?

The FabScanPi will need 12V DC and 5V DC. There are different options to fulfil this requirement:

Option A: Connect 12V DC to the HAT (round connector) and install a 12V DC - to - 5V DC regulator on the designated space on the HAT.

NOTE: For details and specifications please consult the hardware chapter.

Option B: Connect 12V DC to the HAT (round connector) and 5V DC to the raspberry (micro USB connector).

NOTE: Make sure you switch on the both power sources at the same time to avoid software trouble.

Option C: Connect 12V DC to the HAT (round connector) and connect a 5V DC power source to the 5V pin regulator pin on the HAT.

NOTE: For details and specifications please consult the hardware chapter.

i have a PI3 and i have only 1 powerconnection to the Pi (original) and the scanner works perfekt. I tryed the extra conection to the HAT for 1 years ago but this is doesnt matter.
