This is arguably the best value servo controller available, with 32 channels of 1uS resolution servo control. Bidirectional communication with Query commands. Synchronized, or "Group" moves. 12 Servo Hexapod Gait Sequencer built in.

The SSC-32 (serial servo controller) is a small preassembled servo controller with some big features. It has high resolution (1uS) for accurate positioning, and extremely smooth moves. The range is 0.50uS to 2.50uS for a range of about 180°. The motion control can be immediate response, speed controlled, timed motion, or a combination. A unique "Group Move" allows any combination of servos to begin and end motion at the same time, even if the servos have to move different distances. This is a very powerful feature for creating complex walking gaits for multi servo walking robots. The servo's position or movement can be Queried to provide feedback to the host computer. There is even a 12 servo Hexapod sequencer built in. This allows complete control of all aspects of the alternating tripod gait simply by transferring a few values from the host controller. Any output can be used as a TTL level output. There are 4 digital inputs that are static or latched, so you don't have to worry about missing a short event. They can also be used as analogue inputs. There are three terminal blocks for powering options. The DB9 input has true RS-232 levels for use with a PC. There is a socket for a 24LC32P EEPROM, which will be used in future versions of the firmware.
