PIC development board suggestions

[Lucky-Luka]

Hi all
I am thinking about designing a PIC development board similar to this one:

I was thinking about 12V 3A power supply for it like this one:

I would like to design a motor driver board to complete this kind of demo board. I was thinking about dc brushed motor and servo motor that usually work at 5-6V and stepper motor at 12V.
What do you think the power part should look like?
Maybe a buck converte 12v-6v and a low dropout regulator to power the PIC and other peripherals at 5V?
The power part of the aforementioned board I think is not the best solution...

Any suggestions will be greatly apreciated.
