The Motoron M2S family of dual high-power motor controller shields makes it easy to independently control two bidirectional, brushed DC motors with an Arduino or compatible board, such as the A-Star 32U4 Prime. Unlike most of Pololu's motor drivers and motor driver shields, the Motoron does not require any PWM outputs or timers on your Arduino. Instead, the Arduino communicates with the Motoron using I²C, so only two I/O lines are needed. Four types are available so you can pick the one with the appropriate operating voltage range and output current capabilities for your project:

Available versions:

Each of the four types above is available in three versions to provide different options for the through-hole connectors: they can be purchased as an assembled product with stackable headers and terminal blocks soldered in, as a kit with connectors included but not soldered in, or as a standalone board without connectors.

For a lower-power, lower-cost alternative Arduino shield, please consider the Motoron M3S256 Triple Motor Controller Shield for Arduino.

Motoron M2S24v14 Dual High-Power Motor Controller Shield Kit for Arduino.

Motoron M2S24v14 Dual High-Power Motor Controller Shield for Arduino, top view.

The M2S24v14 shield operates from 6.5 V to 40 V (absolute maximum, not intended for use with 36 V batteries) and can deliver continuous output currents up to 14 A per motor. The M2S24v14 can be distinguished from other types of M2S shields by its smaller discrete MOSFETs and the number 100 on top of the tall silver electrolytic capacitors.

This version is a kit with the following connectors included but not soldered in:

  • One 1×10 stackable female header
  • Two 1×8 stackable female headers
  • One 1×6 stackable female headers
  • Three 2-pin 5mm screw terminal blocks (see the terminal block warnings below)
  • Two 1×20 male headers (or some other configuration with a total of 40 pins)

This board is also available with connectors soldered, or as a standalone board without connectors.

The terminal blocks on the Motoron M2S high-power motor drivers are taller than the headers, so Pololu should only be installed on the top Motoron in the stack.

Terminal block warnings:
1) The 5mm blue terminal blocks are rated for up to 16 A, so for higher-current applications Pololu recommend getting an unsoldered version and then soldering thick wires directly to the board.
2) The included terminal blocks are taller than the headers, so a Motoron M2S shield assembled with 5mm terminal blocks is meant to be used as a standalone board or at the top of a shield stack. (Trying to stack multiple shields with terminal blocks can result in short circuits between the stacked terminal blocks.)

  • Comprehensive user’s guide

Real-world power dissipation consideration

The MOSFETs can handle large current spikes for short durations (e.g. 100 A for a few milliseconds), and the driver’s current chopping will keep the average current under the set limit. The peak ratings are for quick transients (e.g. when a motor is first turned on), and the continuous rating is dependent on various conditions, such as the ambient temperature. PWMing the motor will introduce additional heating proportional to the frequency. The actual current you can deliver will depend on how well you can keep the motor driver cool. The driver’s printed circuit board is designed to draw heat out of the MOSFETs, but performance can be improved by adding a heat sink or air flow. For high-current installations, the motor and power supply wires should also be soldered directly instead of going through the 5mm blue terminal blocks, which are rated for up to 16 A.

Warning: This motor driver has no over-temperature shut-off. An over-temperature or over-current condition can cause permanent damage to the motor driver. You might consider using either the shield’s current sense or an external current sensor to monitor your current draw.

This product can get hot enough to burn under normal operating conditions. Take care when handling this product and other components connected to it.

The Motoron family

The table below lists the members of the Motoron family and shows the key differences among them. Each type is available in three versions to provide different options for the through-hole connectors: they can be purchased as an assembled product with stackable headers and terminal blocks soldered in, as a kit with connectors included but not soldered in, or as a standalone board without connectors.
