Your connector isn't soldered in.

Move the 7805 to the back of the PCB.
Add 47 Ohm and a bypass cap to the front of the regulator.
I have done this on my RaduinoX PCB, as well as Bolting the regulator to
a ground heat sink with a 6-32 screw in nut.
No heat problem after that. No need for another regulator.
This should have been done originally.
Here is a picture of RaduinoX. Many problems Fixed. USB on the other
side. More connectors.

My approach is to add a 7808 regulator at the power input, so the
voltage drop is in two stages. This would feed only the "12V" input
to the main circuit. The "PA12"
would still be fed from the power supply input.
