Elecrow's new design of a TB6612 motor shield, which allows to use the most simple and effective way to drive DC motors and stepper motors. This shield can meet your requirements, it can drive four DC motors or two stepper motors, and we have other improvements:

TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time), its motor voltage is low, so you get more power out of your batteries, and there are Built-in flyback diodes as well.

Stackable design and 5 address-select pins allow it to stack up to 32 shields so that you can control 128 DC motors and 64 stepper motors that you can use to complete any Arduino project you want.

Features

• 2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer
• 4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A for brief 20ms peaks) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
• Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
• Motors automatically disabled on power-up
• Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping. Crowtail interface
• Big terminal block connectors to easily hook up wires (18-26AWG) and power
• Arduino power button
