Micro Gearmotor - 270 RPM (6-12V) Product Help and Resources
Core Skill: Robotics
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.
See all skill levels
Core Skill: Electrical Prototyping
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: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

Using for prototype mechanism.
On first try we found there was plenty of torque for the application we are building.Will know more after the beta version is complete.

Extending the Shaft of the Microgear Motor
If you are looking for a way to extend the microgear motor's shaft to add an encoder, feel free to use the Shaft Coupler - 1/4" to 3mm [ https://www.sparkfun.com/products/12412 ]. You would just need to find a shaft length that is suitable for your project. Here's an example from ServoCity using a shaft coupler with a micro gearmotor => [ https://www.servocity.com/media/catalog/product/cache/1/image/438x280/602f0fa2c1f0d1ba5e241f914e856ff9/c/o/coupler_on_gearmotor_with_shafting.jpg ].
Can I get a Data Sheet for this motor?
I really could use a data sheet for shape and dimensions.
Is a drawing or model available for this family of parts?
Is this powerful enough to run a small robot?
You need to estimate the load to determine that...take some guesses, apply some physics. Have fun!
Hrm could you put up something on how to wire this sucker up?
As a general rule a DC motor only needs a power connection. Apply 6-12V to the motor (VCC to one pin and GND to the other) and it should spin. If you have any other questions feel free to email techsupport@sparkfun.com
Excellent!!! Simple!!! I love it! Thanks for the help!
