These are standard '130 size' DC hobby motors. They come with a wider operating range than most toy motors: from 4.5 to 9VDC instead of 1.5-4.5V. This range makes them perfect for controlling with an Adafruit Motor Shield, or with an Arduino where you are more likely to have 5 or 9V available than a high current 3V setting. They'll fit in most electronics that already have 130-size motors installed and there's two breadboard-friendly wires soldered on already for fast prototyping
This motor is not as electrically noisy as the FA-130 motor used in many of the Tamiya gearboxes, and it draws much less current. The two motors are the same size and have similar output power, but, with double the voltage and half the current, these units are generally more convenient to use. If you would like to use lower-current motor controllers with the Tamiya gearboxes, you can simply replace the original Tamiya motor with this and you’ll be set! We have this Dual Motor Gearbox and you can replace the motors with this DC 130 size motor.
