If you are thinking of creating/controlling a robot, i would suggest you use the SSC-32. You can get it from lynxmotion or bizoner. Actually, i got myself one and i am planning on using it to control a robot arm using a joystick. Trust me, it will be fun. I will post the project once it is done, so stay tuned.
Before you start using the SSC-32 it is important to understand all its features and specifications. This enables you to know how the SSC-32 works. In addition to this, you should know how to power it.
There are different ways through which you can power your SSC-32. If you are working on a small project that will be running for a short while, it is advisable to use one power source. The connection is shown in the images above. The jumpers VL=VS1 and VS2=VS1 should be connected and the board should be powered through the VS1 terminals.
If your project has many servos and is meant to operate for a longer time, i would suggest you use alternative powering options. Visit this link, SSC-32 Powering options, to see the different options that you can use before you get started.
