Big terminal block connectors to easily hook up wires (18-26AWG) and power.Motors automatically disabled on power-up.Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution).4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A for brief 20ms peaks) with thermal shutdown protection, internal kickback protection diodes.2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer - no jitter!.This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.Ĭompletely stackable design: 5 address-select pins means up to 32 stackable shields: that's 64 steppers or 128 DC motors! Features Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This chip handles all the motor and speed controls over I2C. Instead of using a latch and the Arduino's PWM pins, it has a fully-dedicated PWM driver chip onboard. It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well. This shield will make quick work of your next robotics project! It's able to drive up to 4 DC motors or 2 stepper motors with TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time).
