Mini maestro 24 servo controller
Ohh, sorry matey, I completely missed this in your original post
Please ignore my question
For the most part, they are the same thing in the way they can both be programmed to control servo motors.
A dedicated servo controller, though, can usually control a significantly larger amount of servos.
(For example, -most- Arduino boards (which is more or less just an ATmega MC and the parts needed to run it) can control only 12 servos [Except the Arduino Mega, which can control 48])
I've been going about my hexapod much differently, using multiple microcontrollers communicating via I2
It may turn out that I would have been better off going with an option similar to yours, but I'm still hoping I can keep the size somewhat small - fitting in 2-3 palms, perhaps...
