I’m interested in building something to test servos. Part of this will need a servo controller, preferably controlled over USB by the host computer. The controller would need to support maximum precision currently out there for RC servos, and ideally generate up to a 333hz command stream rather than just 50hz. Is there a product for this?
Our newest servo controller, the Micro Maestro, satisfies most of your requirements except the 333Hz pulse rate. The Micro Maestro can go up to 100Hz on four channels, which is faster than most servo controllers. We hope to release a new servo controller in another month or so that can get to 333Hz or at least close to it.
