Not 100% I understand what you’re asking, so to be a bit broad:
The SSC-32U is a dedicated servo controller which takes signals from either: USB; Serial (Tx / Rx) or XBee. It’s not programmable and needs an external device providing the motion signals which it then converts to repeated servo PWM pulses. It needs a power supply connected to VS1 (and/or VS2 if you have many servos) which matches what your RC servos need. In most cases a 6V power supply (battery or wall adapter) works for RC servos.
Therefore yes, the only connections to the SSC-32U would be USB and power, and it can easily control 9 servos. If I didn’t understand correctly, can you clarify? Hope this helps.

Ok, so to make my 9 servos work, I just need this board connected via usb to a pc and a 6 volt power supply, correct? Is this a better solution rather than a PCA9685 16 channel 12 bit board and a separate microcontrol board?

It’s a physically smaller board, and made for the Grove system. If you’re using other parts from Seeedsudio Grove, then certainly consider it as all parts operate off the same communication bus. If not, thenyou might find the simplifity of the communication protocol of the SSC-32U to be advantageous.
