5v/3.3v PS PCB

  Here is a simple but versatile power supply board.
It uses either a TO-220 7805 or a TO-92 78L05 (or other voltages).
Power LED is optional,  and can be on-board or remote with a header.
Power switch is optional, install a 2-pin header and cut the trace between it.
I usually use the power jack and cut a hole in the side of a case, then hot glue and black RTV to hold it.
There is a power in 2-pin header as well as 2.1mm power jack.
Headers are of course optional, just solder wires in the holes.
