Frequently asked questions
What voltage should I power it from?
The listed ratings are at 6 V, so power it from a 6 V source or within the range your motor driver supports. Account for the 420 mA stall current when choosing the driver and supply.
How do I control its direction?
Reverse the polarity of the two motor leads to reverse rotation. For speed and direction control from a microcontroller, use a motor driver such as an H-bridge that can supply the stall current.
