DC/Stepper Motor Driver Product Description

With the TB6612, you can spin two DC motors, step one bi-polar or uni-polar stepper, or fire off two solenoids with 1.2A. If you want to control motors without a shield or HAT, these are easy to include on any solderless breadboard or perma-proto.

Each breakout chip contains two full H-bridges (four half H-bridges). That means you can drive 2-4 solenoids (only two can be active at a time, on opposite bridges), two DC motors bi-directionally, or one stepper motor. Just make sure they're good for 1.2 Amp or less of current, since that's the limit of this chip. They do handle a peak of 3A but that's just for a short amount of time, like 20 milliseconds.

There’re two digital inputs per H-bridge (one for each half of the bridge) as well as a PWM input per driver so you can control motor speed. Runs at 2.7V-5V logic. The motor voltage is separate from the logic voltage. Good for motor voltages from 4.5V up to 13.5V! This won’t work well for 3V motors.
