Support Sawppy via Amazon Associates Program

Sawppy the Rover is a project done out of love of our interplanetary robotic explorers Curiosity and Perseverance. Sawppy's design and instructions for construction are shared with other rover lovers free of charge under the permissive MIT license.

Some very generous people have offered to donate to help the project. I have declined offers of direct donation, but I have set up an Amazon Affiliates account based on suggestion. If an aspiring rover builder buys components from Amazon (USA) using the links below, they will pay the same price but Amazon will send a (very small) percentage of the sale to me as sales commission. Here is the boilerplate disclosure: As an Amazon Associate I earn from qualifying purchases.

I have other links to Amazon products scattered throughout Sawppy documentation, but they are generic links that do not earn commission. This is the only page with affiliate links.
