Datasheet

We solder on TB6612 onto a breakout board for you here, with a polarity protection FET on

the motor voltage input and a pullup on the "standby" enable pin. Each breakout chip

contains two full H-bridges (four half H-bridges). That means you can drive four solenoids,

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, about 20 milliseconds. What we like most about this

particular driver is that it comes with built in kick-back diodes internally so you dont have to

worry about the inductive kick damaging your project or driver!
