The Adafruit TB6612 Breakout is a compact dual H-bridge motor driver that can spin two DC motors bidirectionally, step one bipolar or unipolar stepper, or fire two solenoids — all at up to 1.2A continuous per channel (3A peak). It's the same driver chip used in the Adafruit Motor Shield and Motor HAT, now in a breadboard-friendly breakout format.

The board includes a polarity protection FET on the motor voltage input, a pull-up on the standby/enable pin, and built-in kickback diodes — so you don't need external flyback protection for inductive loads.

Key Features

• TB6612 Dual H-Bridge – Two full H-bridges (four half H-bridges)
• 1.2A Continuous / 3A Peak – Per channel
• PWM Speed Control – One PWM input per driver for variable speed
• Motor Voltage – 4.5–13.5V (separate from logic)
• Logic Voltage – 2.7–5V
• Built-In Kickback Diodes – No external flyback protection needed
• Polarity Protection – FET on motor voltage input
• Breadboard-Friendly – Includes header strip
