ServoCity 2x40A Motor Controller
Description
- ServoCity 2x40A Motor Controller
- Handles continuous 40A current per channel
- Equipped with temperature and voltage protections
- Fits seamlessly with goBILDA® 8mm grid
- Supplies power through an XT90 connector
- Accepts PWM signals from various devices
The ServoCity 2x40A Motor Controller is a dual-channel device designed to proportionally manage the speed and direction of up to two Saturn Planetary Gear Motors per channel. It is engineered to handle a continuous current of 40A per channel, with a peak capacity of 50A. The controller is equipped with advanced safety features, including temperature, current, and reverse-voltage protections, ensuring reliable operation. Status LEDs provide real-time feedback on signal reception and any potential errors related to current, voltage, or temperature. The design includes a signal arm zone to prevent unintended motion, and its compact form factor allows for easy integration into various projects. The aluminum heatsink serves as a mounting base, featuring M4 threaded holes compatible with the goBILDA® 8mm grid pattern for seamless attachment to other components. Power is supplied through an XT90 connector, accommodating a voltage range of 9-30V, and can be sourced from any suitable battery. The controller accepts PWM servo-signals from an RC receiver, Arduino, or similar devices, with a built-in BEC providing 6.2V and up to 6A to power servos and other devices without requiring an additional battery. The motor controller's output is facilitated through bullet connectors, allowing for flexible wiring configurations to power multiple motors, provided the current limit per channel is not exceeded. Note: Ensure proper handling to avoid exceeding current limits and adhere to safety guidelines to prevent damage or injury.

Refund Policy
If you are not satisfied with a product purchased from the Site, you may request a return within 30 days from the delivery date, unless the product is listed under the Return Exceptions below or is subject to specific return conditions noted on the product page.
This return policy also applies, as a minimum standard, to products sold and fulfilled by third-party vendors through the Marketplace.

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.
- 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 fulfil a customer request.
- Professional & Specialized Equipment — See the Professional & Specialized Equipment Warranty page and Professional & Institutional Buyers (B2B) section in the Terms & Conditions.
* United-Kingdom consumers retain their statutory Right of Cancellation on these items. Its exercise is subject to the conditions and exclusions set out in the Statutory Right of Cancellation, and any reimbursement may be reduced to reflect a loss in value resulting from handling beyond inspection.
How to Request a Return Authorisation (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]".
