The Adafruit Solenoid / Stepper Motor Driver Breakout Board is a versatile high current driver able to control 2 x bidirectional DC motors, 1 x stepper motor or 2 x solenoids. It uses a TB6612 dual H-bridge chip that can supply 1.2A, which isn't that high in real terms but it's a huge current compared to the recommended 20mA output from an Arduino GPIO pin for example. The chip has built-in flyback diodes to prevent damage due to inductive kick-back and Adafruit have added reverse polarity protection on the motor power input as well. The H-bridges are disabled at power-up to prevent twitching when power is applied. All the logic inputs are 3.3 to 5V compatible so you can run the driver board from an Arduino or Raspberry Pi, while the motor power has a separate input from 4.5 to 13.5V DC. There's a separate PWM input on each H-bridge so that you can control the motor speed.
Supplied as an fully assembled and tested board plus a strip of 0.1in. header pins for you to solder on as required. Adafruit supply a free tutorial to get you started. An ideal board for those times when you just want to get something working quickly.
