The TB6612 Dual H-Bridge Motor Driver Breakout lets you easily control two DC motors, a single stepper, or two solenoids at up to 1.2 A per channel (3 A peak). Featuring built-in kickback diodes, polarity protection, and 2.7–5 V logic support, it’s perfect for breadboard or perma-proto motor projects without needing a shield or HAT.
Spin two DC motors, step one bi-polar or uni-polar stepper, or fire off two solenoids with 1.2A per channel using the TB6612. These are perhaps better known as "the drivers in our assembled Adafruit Motorshield or Motor HAT." We really like 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.
We solder on TB6612 onto a breakout board for you here, 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 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. What we like most about this particular driver is that it comes with built-in kick-back diodes internally so you don't have to worry about the inductive kick damaging your project or driver!
There are 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.
Comes as one assembled and tested breakout plus a small strip of header. You'll need to do some light soldering to attach the header onto the breakout PCB. Arduino, motors, and power supply not included. Check out our handy tutorial on assembly and wiring!
As of December 5, 2022 We have updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.
