- Compatible with Arduino Portenta and MKR families
The Arduino Portenta C33 is a streamlined module that offers the high performance of the Portenta family at a lower price point, thanks to optimizations and streamlined features. While its secure element guarantees industrial-grade security at the hardware level, the Portenta C33 is also able to perform over-the-air firmware updates with Arduino IoT Cloud or other third-party services.
Ideal to develop cost-effective, real-time applications, Portenta C33 features the Arm Cortex-M33 microcontroller by global leader Renesas and supports MicroPython and other high-level programming languages. Thanks to its onboard Wi-Fi and Bluetooth Low Energy connectivity, the module stands out as an ideal solution for IoT gateways, remote control systems, fleet management, and process tracking.
Quickly deploying AI-powered projects becomes quick and easy with Portenta C33, by leveraging a vast array of ready-to-use software libraries and Arduino sketches available, as well as widgets that display data in real-time on Arduino IoT Cloud-based dashboards. What’s more, the module’s form factor is compatible with the Portenta and MKR ranges and features castellated pins - ready for automatic assembly lines and more efficient connections to other components.

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.
- Professional & Specialized Equipment — See the Professional & Specialized Equipment Warranty page and Professional & Institutional Buyers (B2B) section in the Terms & Conditions.
How to Request a Return Authorization (RA)
While the same return policy applies, these orders require a separate contact process for returns.
- RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
- Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
