N20 DC Motor with Magnetic Encoder - 6V with 1:298 Gear Ratio

The first step in a robotics project is to get a motor spinning. Once you've done that you quickly learn that not all motors go the same speed, even if they are the same part number! There are always variations that relate to voltage, environment, and manufacturing changes.

White motor lead
Motor drive lead. Adafruit states to provide 4.5 to 6V DC nominal to the white and red wires via a motor driver; these leads can be PWM controlled and reversed with an H-bridge.
