These are a pair of right angle, hobby gearmotors from DAGU. These gearmotors are the same ones utilized in the Magician Chassis and RedBot Kit and offer a cheap and easy to use setup to get your wheels turning. Due to these gear motors being at a right angle, you will also be able to track and control the rotation of your wheels!
Each gearmotor requires a voltage of 3-6V with a no load current of 200mA while possessing a stall current of 3A@6V (1.5A@3V), a gearbox ratio of 48:1, and a wheel speed of 65 rpm at 3V unloaded.
These gearmotors are sold in packs of two.
This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.
Skill Level: Rookie - You will be required to know some basics about motors, basic motor drivers and how simple robotic motion can be accomplished.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Trying to gear down an RC motor is huge pain. These take care of the problem with a 48:1 gear ratio.
These worked great for building a small robot/car

The motors I received (5/4/19) do not match the published specs. At 3V, no load, they are approximately 140RPM and draw about 80mA. The specs listed on DAGU's website are conflicting as well. They list the (roughly) correct info in the text portion of their site, and the same info as Sparkfun's description in the image portion.

Please post a new topic on our forums so that our technical support team can assist with this product issue. (*I'll try to remember to let them know tomorrow. Posting on the forums will get you the quickest response.)
is there an easy way to mount these to an Actobotics channel? Thanks!
These don't appear to be the same motors as stated in the description for the Magician chassis. The data sheets don't match and I don't see a shaft for an encoder.
What about the physical orientation of these motors makes them more apt to track? Is there a prescribed encoder set-up?
Edit: The complete kits sold here (and mentioned in the product video) include encoders with magnets and hall effect sensors that mount to the gearbox bodies, but they seem specially designed for each other, so I would skip these and go with the kit if I was looking to use encoders.
The metal tabs on these have a tendency to get torn off, I would recommend using hot glue to secure them once soldered.
