This is a rail to rail, meaning about a 5.11 volts peak to peak nice
square wave, with its bottom sitting on the ground rail. Can I feed
that without any further treatment, into the + terminal, pin 2 of your
pwm-servo? Or at 5 volts, do I need a protective R in that wire?
The PWM servo amp takes a plus on the plus input (TB2-pin 1)
and a negative on TB2-pin 2
to turn on the transistors. You don't need an external
resistor, that is provided in the servo amp.
Just be sure when you want the spindle off, that pin 1 is
not getting the positive voltage.
