Hey CD, I’ve been trying to get this Andy Mark “Thrifty Throttle” operational for our team to test with. From what I’ve read here using it on a speed controller is pretty straight forward and not too worried about that part. However, our team is looking to test with servos. I’ve tried externally powering a few servos while using the thrifty throttle, but to no avail. Has anyone gotten this working with servos? If so, how?
Thanks everyone!
no clue:( 
From the user manual you linked:
NOTE: This unit produces a PWM signal only; it does not supply power to
devices. Devices such as servos, speed controllers etc. need a separate power
supply.
What sort of power supply are you using to power the servos? It should be 5-6 V.
Did you connect the ground of the power supply for the servo to the ground of the Thrift Throttle. The control signal to the servo needs a common reference to the power for the servo. Is your servo power adequate? They can draw a bit of current.
The little note at the bottom of the document you linked to says:
“NOTE: This unit produces a PWM signal only; it does not supply power to
devices. Devices such as servos, speed controllers etc. need a separate power
supply”
No power on the middle pin to power the servo. There’s you problem right there.
Hey, here’s what I tried the other week and all I got was some strange jittering from servos.

SuperBK, according to your post, is all I need to do is use configuration 2 on my image and connect ground in there?
Which servo is it? Some servos may require 6V to operate.
