Hi,
For my arduino controlled preamp I've designed a small power splitter PCB to feed all the parts of control peripherals, e.g. R-2R relay based volume controller, input selector, arduino board itself, etc. The bottom layer is a ground plane the top layer is a power plane. The board size is 3x3 cm. Mounting holes are on 10 mm grid. The image of the PCB (top and bottom) and an example of possible connections are attached. All connectors are electrically in parallel to each other.
Sold.
Regards,
Oleg
