Using this 130 DC motor module is easy. First, connect it to your project using the Gravity 3 - pin digital cable. Since it has an integrated transistor, you don't have to worry about adding a motor driver. You can control the motor using PWM. For the best results, make sure the operating voltage is set to 5V. When handling the module, be gentle as it's quite light at 40 grams. Avoid dropping it or applying excessive force. To keep it in good condition, store it in a dry place when not in use.
