Today my 12 volt to 5 volt regulator arrived from Dimension Engineering.
Since I am not the best with the soldering iron, I opted for the breakout board option so the regulator simply plugs into position.
This will draw power from the RigRunner control panel and power the servo power for the ServoCenter controller card. With so many servos in use, the card needs external power for the servos, which is 5 volt.
Also...I wanted to mention and remind everyone that the second R2-D2 is well into production. You can follow the progress here...
