The M2H controllers are designed to stack on top of a Raspberry Pi (Model B+ or newer), similar to a HAT (Hardware Attached on Top), and multiple controllers can be stacked on top of each other, allowing independent control of many motors. Unlike most of Pololu's [motor drivers](https://core-electronics.com.au/breakout-boards-and-modules/motor-drivers-controllers/brushed-dc-motor-drivers.html) and motor driver [expansion boards for Raspberry Pi](https://core-electronics.com.au/catalogsearch/result/?q=pi+motor), the Motoron does not require any PWM outputs on your Raspberry Pi. Instead, the Raspberry Pi communicates with the Motoron using I²C, so only two GPIO pins are needed regardless of how many Motorons you connect. The **M2H24v14** controller operates from **6.5 V to 40 V** (absolute maximum, not intended for use with 36 V batteries) and needs to be provided with an external power source. This driver will not work directly from the power provided by the Raspberry Pi. Four types are available so you can pick the one with the appropriate operating voltage range and output current capabilities for your project: | | [![](https://core-electronics.com.au/attachments/localcontent/0J11750_53354ff59d.jpg) Motoron M2H18v20 Dual High-Power Motor Controller for Raspberry Pi](https://core-electronics.com.au/motoron-m2h18v20-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) | [![](https://core-electronics.com.au/attachments/localcontent/0J11748_5610a25f07.jpg) Motoron M2H18v18 Dual High-Power Motor Controller for Raspberry Pi](https://core-electronics.com.au/motoron-m2h18v18-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) | [![](https://core-electronics.com.au/attachments/localcontent/0J11751_5485f2f3d2.jpg) Motoron M2H24v16 Dual High-Power Motor Controller for Raspberry Pi](https://core-electronics.com.au/motoron-m2h24v16-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) | [![](https://core-electronics.com.au/attachments/localcontent/0J11749_5640c9f7f0.jpg) Motoron M2H24v14 Dual High-Power Motor Controller for Raspberry Pi](https://core-electronics.com.au/motoron-m2h24v14-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) | |---|---|---|---|---| | Absolute max input voltage: | 30 V | 40 V | | Max nominal battery voltage: | 18 V | 28 V | | Max continuous current per channel: | 20 A | 18 A | 16 A | 14 A | | Available versions: | - [assembled](https://core-electronics.com.au/motoron-m2h18v20-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) - [kit](https://core-electronics.com.au/motoron-m2h18v20-dual-high-power-motor-controller-kit-for-raspberry-pi.html) - [board only](https://core-electronics.com.au/motoron-m2h18v20-dual-high-power-motor-controller-for-raspberry-pi-no-connectors-or-standoffs.html) | - [assembled](https://core-electronics.com.au/motoron-m2h18v18-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) - [kit](https://core-electronics.com.au/motoron-m2h18v18-dual-high-power-motor-controller-kit-for-raspberry-pi.html) - [board only](https://core-electronics.com.au/motoron-m2h18v18-dual-high-power-motor-controller-for-raspberry-pi-no-connectors-or-standoffs.html) | - [assembled](https://core-electronics.com.au/motoron-m2h24v16-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) - [kit](https://core-electronics.com.au/motoron-m2h24v16-dual-high-power-motor-controller-kit-for-raspberry-pi.html) - [board only](https://core-electronics.com.au/motoron-m2h24v16-dual-high-power-motor-controller-for-raspberry-pi-no-connectors-or-standoffs.html) | - [assembled](https://core-electronics.com.au/motoron-m2h24v14-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) - [kit](https://core-electronics.com.au/motoron-m2h24v14-dual-high-power-motor-controller-kit-for-raspberry-pi.html) - [board only](https://core-electronics.com.au/motoron-m2h24v14-dual-high-power-motor-controller-for-raspberry-pi-no-connectors-or-standoffs.html) | 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. | [![](https://core-electronics.com.au/attachments/localcontent/0J11736_465521a8973.jpg)](https://core-electronics.com.au/attachments/localcontent/0J11736_108736809f0.png) | |---| For a lower-power, lower-cost alternative, please consider the [Motoron M3H256 Triple Motor Controller for Raspberry Pi](https://core-electronics.com.au/motoron-m3h256-triple-motor-controller-for-raspberry-pi-connectors-soldered.html).

As shown in the picture below, the terminal block pins should be trimmed, and the nuts included with the standoffs can be used as extra spacers. | [![](https://core-electronics.com.au/attachments/localcontent/0J11763_538041ebf76.jpg)](https://core-electronics.com.au/attachments/localcontent/0J11763_242195e93c1.jpg) | |---| | Two Motoron M2H boards with terminal blocks can be stacked if you trim the leads on the terminal blocks and space out each board using hex nuts in addition to the 11mm standoffs. | | [![](https://core-electronics.com.au/attachments/localcontent/0J11737_31840de299e.jpg)](https://core-electronics.com.au/attachments/localcontent/0J11737_20585025a89.png) | |---| | Motoron M2H Dual High-Power Motor Controller for Raspberry Pi pinout. | **Features and specifications** - Two motor control channels allow for independent control of up to two bidirectional brushed DC motors - Reverse-voltage protection on motor power supply - Logic voltage range: 3.0 V to 5.5 V - Control interface: I²C - I²C clock speed: up to 400 kHz - Optional cyclic redundancy checking (CRC) - Configurable motion parameters: - Max acceleration/deceleration forward/reverse - Starting speed forward/reverse - Direction change delay forward/reverse - PWM frequency: eight options available from 1 kHz to 80 kHz - Current sensing - Configurable hardware current limiting - Command timeout feature stops motors if the Raspberry Pi stops functioning - Configurable automatic error response - Motor power supply (VIN) voltage measurement - Optional pins make it easy to power the Raspberry Pi from reverse-protected motor power through an [external regulator](https://core-electronics.com.au/components/voltage-regulators.html) (not included) - Two status LEDs - Motor direction indicator LEDs - [Motoron Python library](https://github.com/pololu/motoron-rpi) simplifies getting started using the Motoron with a Raspberry Pi - Comprehensive user’s guide | [![](https://core-electronics.com.au/attachments/localcontent/0J11761_7776366d0e8.jpg)](https://core-electronics.com.au/attachments/localcontent/0J11761_70418a4c8c7.jpg) | |---| | Two Motoron M2H shields stacked on a Raspberry Pi. | **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 Motoron’s current sense or an [external current sensor](https://core-electronics.com.au/acs711ex-current-sensor-carrier-31a-to-31a.html) 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. | Motoron Motor Controllers | |---| | | | | [![](https://core-electronics.com.au/attachments/localcontent/0J11626_2962be2656.jpg) M3S256](https://core-electronics.com.au/motoron-m3s256-triple-motor-controller-shield-for-arduino-connectors-soldered.html) [![](https://core-electronics.com.au/attachments/localcontent/0J11674_3209e6efee.jpg) M3H256](https://core-electronics.com.au/motoron-m3h256-triple-motor-controller-for-raspberry-pi-connectors-soldered.html) | [![](https://core-electronics.com.au/attachments/localcontent/0J11709_53087bff09.jpg) M2S24v14](https://core-electronics.com.au/motoron-m2s24v14-dual-high-power-motor-controller-shield-for-arduino-connectors-soldered.html) [![](https://core-electronics.com.au/attachments/localcontent/0J11749_5640c9f7f0.jpg) M2H24v14](https://core-electronics.com.au/motoron-m2h18v20-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) | [![](https://core-electronics.com.au/attachments/localcontent/0J11724_5067aba0d8.jpg) M2S24v16](https://core-electronics.com.au/motoron-m2s24v16-dual-high-power-motor-controller-shield-for-arduino-connectors-soldered.html) [![](https://core-electronics.com.au/attachments/localcontent/0J11751_5485f2f3d2.jpg) M2H24v16](https://core-electronics.com.au/motoron-m2h24v16-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) | [![](https://core-electronics.com.au/attachments/localcontent/0J11708_5157f41dc0.jpg) M2S18v18](https://core-electronics.com.au/motoron-m2s18v18-dual-high-power-motor-controller-shield-for-arduino-connectors-soldered.html) [![](https://core-electronics.com.au/attachments/localcontent/0J11748_5610a25f07.jpg) M2H18v18](https://core-electronics.com.au/motoron-m2h18v18-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) | [![](https://core-electronics.com.au/attachments/localcontent/0J11723_513556771e.jpg) M2S18v20](https://core-electronics.com.au/motoron-m2s18v20-dual-high-power-motor-controller-shield-for-arduino-connectors-soldered.html) [![](https://core-electronics.com.au/attachments/localcontent/0J11750_53354ff59d.jpg) M2H18v20](https://core-electronics.com.au/motoron-m2h18v20-dual-high-power-motor-controller-for-raspberry-pi-connectors-soldered.html) | | Motor channels: | triple (3) | dual (2) | | Max input voltage: | 48 V | 40 V**1** | 30 V**1** | | Max nominal battery voltage: | 36 V | 28 V | 18 V | | Max continuous current per channel: | 2 A | 14 A | 16 A | 18 A | 20 A | | Available versions for Arduino: | **M3S256**- [assembled](https://core-electronics.com.au/motoron-m3s256-triple-motor-controller-shield-for-arduino-connectors-soldered.html) -
