no,this is wrong. The servo output is J2 - 9, not J2 - 15.

you need a 5 volt source to power the servo. The Handy Board 5 volt
supply can be used, but this will put a lot of stress on the system
regulator.
It would be better to get a separate battery, or take a tap at the 6
volt point within the internal battery that.

Where it you get the idea that the output is connected to position 15?
I don't know where that would be shown. Any way, it's position 3,
which is labeled sensor input 9.
