90 day unmodified return policy

If you are not 100% satisfied with your order, we will be happy to authorize a return for any unused and unmodified items purchased within 90 days.

Modified product return policy

If you have modified your part and something goes wrong or you aren’t satisfied with your item, our fantastic team of dedicated technicians can help trouble shoot and offer advice to determine if your parts are defective.

In the event that something is determined to be a manufacturer error or failure due to defective materials, we will repair, return or exchange the item(s) as needed.

Damaged in Shipment

Please email right away. Include a description of the damages and pictures of the damaged items/packaging. This information is very helpful to us in assessing how we package our orders and helps prevent similar problems in the future. Replacements will be arranged with Customer Service as needed.

General Return Guidelines

  • All RMAs must be authorized with us prior to sending any returns back.

  • Returns must include any accessories, documentation, etc. included with the product. Your return may be denied if incomplete or damaged.

  • Please do not remove, desolder, or otherwise modify any connected items before contacting Tech Support. We are here to help!

  • Eligibility for return of modified items is determined on a case-by-case basis; we can not guarantee eligibility for modified items.

  • Returns may take up to 2 weeks to process, not including transit times.

  • Replacement orders can not be modified to include different or additional parts.

  • Sparkfun will pay/refund return shipping charges if the damage is found to be related to a manufacture error.

  • Returns for orders older than 90 days are eligible for replacement or store credit only.

  • We reserve the right to limit support, and deny returns on items that were purchased over a year ago, ding and dent items, old version releases, and products not purchased directly from Sparkfun electronics.

  • In the event that your return is not received in restockable condition, we reserve the right deny your return, or change your refund method to store credit only. This is determined on a case-by-case basis.

  • For best service and lowest risk of loss/damage to your return, we suggest that it is sent via a trackable shipping method such as FedEx Ground. Lost packages that are sent via non tracked methods are not guaranteed.

  • No returns should be sent in a flat envelope. The mail system uses rollers to sort the flat packages and crush/damage the items in transit. Please use a box or reinforced padded mailer at a minimum.
