Arduino with SSC32

Hey all, Im new to these forums and just recieved my Duemilanove through the post. I am at the minute just doing some basic programs, altho I have plenty of experience programming in C++, but only in writing software not coding hardware.

I was just wondering, if I got an SSC32 what is the max number of servos I would b able to control using my Arduino? I have never played with servos before.

I am going to have a play with stepper motors next when I get paid but I do have a project in mind using servos.


Hi Cyberstu,

I would say you can control up to 32 servos with the ssc-32 with what I read on the subject. But you can't use the Arduino 5V, you have to provide power from another source. Just don't forget to connect the grounds together (Arduino and ssc-32).

If someone has had experience with this board and the Arduino I'd be glad to hear a little, I'm interested in this board. :)


Here is a website I found explaining how to control the ssc-32 with the Arduino:


I've got an ssc-32connected to my arduino. Simple connection, tx/rx, tx/rx, and gnd/gnd. The ssc-32 board itself could be powered off of the arduino +5v. The servos need their own ~6v power supply.

Sorry, but I’m amazed that you can identify that the SSC32 is what you want without also identifying that it controls 32 servos? ;D

SSC-32 Servo Controller:
Microcontroller = Atmel ATMEGA168-20PU
EEPROM = 24LC32P (Required for 2.01GP)
Speed = 14.75 MHz
Internal Sequencer = 12 Servo Hexapod (Alternating Tripod)
Serial input = True RS-232 or TTL, 2400, 9600, 38.4k, 115.2k, N81
Outputs = 32 (Servo or TTL)
Inputs = 4 (Static or Latching, Analog or Digital)
Current requirements = 31mA
PC interface = DB9F
Microcontroller interface = Header posts
Servo control = Up to 32 servos plug in directly
Servo type supported = Futaba or Hitec
Servo travel range = 180°
Servo resolution = 1uS, .09°
Servo speed resolution = 1uS / Second
Servo motion control = Immediate, Timed, Speed or Synchronized.
PC board size = 3.0" x 2.3"
VS current capacity = 15 amps per side, 30 amps max
