I went through the exercise of designing a new power board that includes a DC power supply. I'm not sure the result is worth doing, though.

I added the footprint for a CUI VSK-S3 AC/DC module and changed the 3 pin screw terminal for a 4 pin one, with the 4th pin being the DC supply out for the controller. The trouble is that the board is now more than twice as large as it was, and the CUI power supply adds around $25 to the retail price - all to save you the trouble of just using a wall wart to power the controller separately.
