I have confirmed my suspisions.
DO NOT run the board AND servos all off the same supply unless you are using a 6VDC supply with plenty of current available. At least a couple amps if you are running multiple servos.
If you connect a 9VDC supply to the VL (or logic) input to the board, that is fine for the board, but if you leave the jumper on that says VL=VS you will burn up your servos.
You can remove that jumper, connect 9VDC to the VL and 5 or 6VDC to the VS and you will be fine. You can also leave the VL=VS jumper on, AND leave the VS1+VS2 jumper on and run the whole thing off 6VDC (with enough amperage)
5 VDC is NOT recommended for VL. It might work, but it is really at the lowest limit and you may experience board resets and problems, Run the VL at a minimum of 6VDC and no more than 9VDC.
I hope that clears up any questions.
