Adafruit TB6612 1.2A DC/Stepper Motor Driver Breakout Board
Fire four solenoids, spin two DC motors or step one bi-polar or uni-polar stepper with 1.2A per channel (3A peak) using the TB6612. These are perhaps better known as "the drivers in Adafruit's assembled Adafruit Motorshield or Motor HAT." Adafruit really likes these dual H-bridges, so if you want to control motors without a shield or HAT these are easy to include on any solderless breadboard or perma-proto. Adafruit solders on TB6612 onto a breakout board for you, with a polarity protection FET on the motor voltage input and a pull up 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. What Adafruit likes most about this particular driver is that it comes with built in kick-back d
