The Pololu Motoron M2H18v20 Dual High-Power Motor Controller Kit for Raspberry Pi is a sophisticated product designed to facilitate the control of DC motors from a Raspberry Pi (Model B+ or newer) via an I2C interface. This kit supports motor supply voltages ranging from 6.5 V to 30 V and is capable of delivering continuous output currents of up to 20 A per motor. This particular version comes with aluminum standoffs, header pins, and terminal block options, which are included but not pre-soldered.
The Motoron M2H series of dual high-power motor controller add-on boards are designed to control up to two bidirectional, brushed DC motors with a compatible Raspberry Pi (Model B+ or newer). These controllers are engineered to stack on top of a Raspberry Pi (Model B+ or newer), akin to a HAT (Hardware Attached on Top), and multiple controllers can be stacked on top of each other, enabling independent control of numerous motors.

The M2H18v20 controller supports motor supply voltages from 6.5 V to 30 V and can deliver continuous output currents up to 20 A per motor. This controller can be identified from other M2H controllers by its larger discrete MOSFETs and the number 150 on top of the tall silver electrolytic capacitors.
This version is a kit that includes but does not pre-solder the following connectors: one 2x20 stackable female header, three 2-pin 5mm screw terminal blocks, and one 1x25 breakaway male header. This header can be cut or broken into smaller header strips for installation as desired. Additionally, the kit includes a set of four M2.5 standoffs (11 mm length), screws, and nuts that can be used to secure the board at the proper height.
Please note that the M2H18v20 controller supports an absolute maximum motor supply voltage of 30 V and is not intended for use with 24 V batteries.

Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
- A valid Return Authorisation (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- The RA number is valid for 30 days. The returned item must be received within that period.
- The RA number must be included with the return.
- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A £100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tyres, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odour-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
- Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
- Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.
