Maestro 6 Channel USB Servo controller by Pololu

The six-channel Micro Maestro raises the performance bar for serial servo controllers with features such as a native USB interface and internal scripting control. Whether you want high-performance servo control (0.25μs resolution with built-in speed and acceleration control) or a general I/O controller (e.g. to interface with a sensor or ESC via your USB port), this tiny, versatile device will deliver. The fully assembled version ships with header pins installed.

Don't forget the Servo Scribe software to make it all work!
