The shield can optionally be configured to power the Arduino from the same power supply as the motor driver, and the Arduino pin mappings can be customized by cutting traces if the defaults are not convenient. This compact expansion board plugs directly into the GPIO header on a Raspberry Pi and provides an easy and low-cost solution for driving a pair of small brushed DC motors. Its pair of integrated MAX motor drivers allows it to operate from 4. The board can deliver a continuous 1. With an operating voltage range from 2.
With an operating voltage range from 0 V to 11 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering up to two small, low-voltage motors.
The carrier board has the form factor of a pin DIP package, which makes it easy to use with standard solderless breadboards and 0. Its integrated DRV dual motor driver allows it to operate from 1. The shield can deliver a continuous 1.
A recommended motor voltage of 4. It is capable of delivering a continuous 0. The driver also features protection against reverse-voltage, under-voltage, over-voltage, over-current, and over-temperature. Its integrated A dual motor driver operates from 6 V to 32 V and can deliver a continuous 0. The A is configured to limit the peak motor current to about 0. With an operating voltage range from 0 V to 11 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering a small, low-voltage motor.
The motor driver features variable switching speed, allowing for PWM frequencies up to kHz, two drive mode options, and built-in under-voltage and over-temperature protection; our carrier also adds reverse-voltage protection.
It can deliver a continuous 1 A 2. This motor driver IC from ST operates from 5. Note: This driver has been discontinued by ST. We recommend the newer and very similar VNH as an alternative. The chip is able to withstand V transients, has a peak current of 30 A, and features various fault protection features such as over-temperature and over-current shutdown. Print Email a friend Feeds.

It ships fully populated with its SMD components, including the two MC ICs, as shown in the picture to the right; stackable Arduino headers and terminal blocks for connecting motors and motor power are included but are not soldered in see the Included Hardware section below. The Arduino pin mappings can all be customized if the defaults are not convenient, and the simplified MC control lines are broken out along the left side of the board, providing a convenient interface point for other microcontroller boards see the right connection diagram below.
This versatility, along with an option to power the Arduino directly from the shield, sets this board apart from similar competing motor shields. Using the dual MC motor driver shield with an Arduino shield and Arduino powered separately.
Using the dual MC motor driver shield with a microcontroller gray connections are optional. For a higher-power alternative to this shield, please consider the dual VNH motor driver shield , which can deliver a continuous 12 A per channel. For lower-power, lower-cost alternatives, consider the dual MAX motor driver shield , DRV dual motor driver shield , or A dual motor driver shield. Pololu dual MC motor driver shield, assembled and connected to an Arduino Leonardo.
Operation from V reduces maximum continuous output current driver performance is derated in this range. See the MC datasheet 1MB pdf for more information. Pololu dual MC motor driver shield for Arduino with included hardware. This motor driver board ships with all of the surface-mount parts populated. However, soldering is required for assembly of the included through-hole parts.
The following through-hole parts are included:. You can also solder wires directly to the board. When not using this board as an Arduino shield, you can solder the 0. However, the chip by itself will typically overheat at lower currents. The actual current you can deliver will depend on how well you can keep the motor driver cool.
PWMing the motor will introduce additional heating proportional to the frequency. Unlike typical H-Bridges, the TBFTG has a feature that allows it to gracefully reduce the maximum current limit when the chip temperature approaches its limit. This means that if you push the chip close to its limit, you will see less power to the motor, but it might allow you to avoid a complete shutdown.
This product can get hot enough to burn you long before the chip overheats. Take care when handling this product and other components connected to it. Print Email a friend Feeds. We have reduced our on-site staff, so for critical requirements, please contact us so we can identify priorities.
