Pololu Dual MC33926 Motor Driver for Raspberry Pi (Partial Kit)
Operates within 5-28 V for broad compatibility
Delivers 3 A continuous, 5 A peak per motor
Includes reverse-voltage protection
Features motor indicator LEDs
Enables customizable GPIO pin mappings
The Pololu Dual MC33926 Motor Driver for Raspberry Pi (Partial Kit) is an expansion board designed to enable a compatible Raspberry Pi (Model B+ or newer) to control two brushed DC motors. It utilizes dual MC33926 motor drivers, which operate within a voltage range of 5 V to 28 V, delivering a continuous current of 3 A per motor, with a peak capacity of 5 A. The board is equipped with a reverse battery protection circuit and logic gates to minimize the number of I/O pins required for effective control.
This partial kit version includes all surface-mount components pre-installed, while the through-hole connectors are provided but not soldered. The board's default configuration employs six GPIO pins for motor control, leveraging the Raspberry Pi's hardware PWM outputs, with two additional pins for reading driver status outputs. Users have the flexibility to customize pin mappings and access other control inputs and outputs for advanced applications.
The board adheres to the Raspberry Pi HAT mechanical specifications, although it lacks an ID EEPROM. It is not compatible with the original Raspberry Pi Model A or Model B due to pinout and form factor differences. The board also features motor indicator LEDs, a prototyping space, and robust drivers with transient operation capabilities and protection against over-current and over-temperature conditions.
Note: This product can become hot enough to cause burns; handle with care.

Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
A valid Return Authorization (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, tires, 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, odor-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.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items * — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
* European consumers retain their statutory Right of Withdrawal on these items. Its exercise is subject to the conditions and exclusions set out in the Statutory Right of Withdrawal, and any reimbursement may be reduced to reflect a loss in value resulting from handling beyond inspection.
How to Request a Return Authorization (RA)
While the same return policy applies, these orders require a separate contact process for returns.
