Can SSC-32 fulfill my requirements?

I tried controlling my johnny 5 with a botboarduino, soon found that it wasn’t possible to use the Servo lib with 17 servos (I have a pan/tilt modded head +1 servo).

So maybe the SSC-32 would be the right replacement… can I:

  1. hold the position of 17 servos
  2. supply 6v 6a to power the whole pcb (1 input for logic and all devices)
  3. add an additional ultrasonic range finder through the SSC

I just want to be 100% sure before I make another purchase, any help is appreciated. Also if I am wrong that I cannot control 17 servos with the botboarduino, let me know. I tried using the SoftwareServo lib (playground.arduino.cc/ComponentLib/servo) which claims it can control 20 servos but when i do – not all my servos are holding position. My sample code is very simple, I’m not at my house but this is really close pseudo code:

#include <SoftwareServo.h>

SoftwareServo servo(1-17)

void setup()
{
Servo(1-17).attach(pin);
Servo(1-17).write(90);
}

void loop()
{
SoftwareServo::refresh();
}

Yes… up to 32 servos in fact.

Yup, but note that the logic voltage ideally operates at 7-12V, so 6V will not be enough. You might consider a voltage regulator:

There are four analog inputs on the SSC-32, so if the rangefinder is analog, you can certainly add it.

We’d suggest using both the BotBoarduino AND the SSC-32 servo controller.
