These specifications are listed with the "rated" values (these are the values where the motor runs at peak efficiency). The motors can deliver considerably more than their rated values, refer to datasheet for more information.

We recommend controlling the motors with one of our motor speed controllers. See our motor controller support page for more information. We also recommend you use our wiring kit to wire your motors. The hookup kit will help suppress the electronic noise generated from any DC motor. See our motor wiring support page for more information.
These heavy duty gearmotors have a rated speed of 4.7 RPM and a gear reduction of 1:1470. They work great on our robots as well as your own applications. These are excellent geared motors for robots.
SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader.
This is a prebuilt RC lawnmower. It is fully assembled and tested and includes the gas mower. This is our Rev 2 Mower chassis. It is faster, more powerful, and has a longer run time.
