DC Motor in Micro Servo Body
PRODUCT ID: 2941
DESCRIPTION
This tiny DC Motor in Micro Servo Body is an interesting motor - it's the same size and shape as
our micro servo 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 an H-bridge
such as a L293D, TB6612 or a Motor shield, Motor HAT or DC Motor + Stepper FeatherWing.

Motor comes with 2x screws and 2x nuts for mounting to a chassis. No flanges or horns
included - it's intended to mate with our little wheels, there's a screw to attach once they're
plugged together. Build a robot vehicle of your own with these little motors driving it!
