This tiny DC Motor in Micro Servo Body is an interesting motor – it’s the same size and shape as our micro servo (like the FS90,FS90R, SG92R) but it isn’t a servo. It’s more like a DC motor + plastic gear-train in a box. It’s not a super powerful motor, it would do well as a little robot wheel. It’s also a lot less expensive than a micro servo (continuous or non-continuous) because there is no control board inside. Controlling speed is done by PWM’ing the power leads, controlling direction is done by swapping the power polarity – just like any brushed DC motor.

Runs from 4-6VDC, we’ve powered it with a Lipoly and 3 alkaline, or 4 NiMH batteries with success. You cannot control this
directly from a microcontroller pin! You must have a H-bridge such as a L293D or motor shield.
Motor comes with 2x screws and 2x nuts for mounting to a chassis. No flanges or horns included – it’s intended to mate with wheels, like our FS90R-W. There’s a screw to attach once they’re plugged together. Build a robot vehicle of your own with these little motors driving it!
