Re: PWM signal driver theory
It's a signal booster. The Victor 884s draw more current on the PWM pin than your standard hobby servo and want nice sharp transitions besides. All the signal driver does is run your incoming PWM signal through some circuitry that spits out the same signal, only with more current drive behind it. So the signal into and out of it is the usual hobby-style servo PWM, but the output signal has better drive circuitry behind it that the Victor with be happier with.
