Servo Motor & Overall Circuit Power Connection Question

Hi,

Just a quick question. I've got a 5VDC power supply that can supply 20A so power is no problem.

The thing is, I need this 5V supply to power up a giant scale servo motor and a wireless receiver I purchased from adafruit. My question is, can this receiver and motor be connected in parallel from the same source or will they cause some kind of interference with each other?

Thanks,
Mike

It's pretty common for servos and receivers to be powered from the same supply. You'll probably be okay using one supply.

You can do things to reduce the noise from the servo. Capacitors are often used for this sort of thing. A couple turns of the servo cable through a ferrite ring would likely reduce the noise from the servo.

What sort of receiver are you using?

I am just using this basic receiver: Keyfob 4-Button RF Remote Control - 315MHz : ID 1095 : $6.95 : Adafruit Industries, Unique & fun DIY electronics and kits

Would you recommend capacitors in parallel to filter out the noise?
