Should I use original board dimensions?

Some other thoughts:

  1. I often use the 2 or 3 screw terminal headers for power in.
  2. Micro USB connectors are terribly fragile. If you decide you need one try to get one with through tabs or at lease a lot of board area for the shield solder connections.
  3. I am liberal with the number of ground pins / terminals etc.
  4. Mounting holes. I try to get at least 3.

When I say 2.54mm connector spacing I'm talking about these (either SMD or through hole)
