In putting together our list of the best Arduino cases to buy, we considered what’s important to think about before you make your decision:

• Compatibility with Arduino: This is hands down the most important requirement. All these enclosures were designed for a specific Arduino model, so they’ll fit every feature and dimension of the board you want to protect. But since your Arduino will rarely be operating in isolation, we also wanted to include some cases that add more features or are compatible with accessories like shields.
• Popularity: When shopping online, you can’t physically see a product for yourself, so other buyer’s reviews are the best indicator you have of whether an item will suit your needs. Here, we’ve focused on enclosures that are popular and credible, reflected by many previous purchasers leaving positive reviews.
• Affordability: There are plenty of enclosures on the market, but we choose ones that were not only popular but also available at an accessible price point.

So, now that we know what we’re looking for, let’s get to the list!

This is a transparent, acrylic case for the Arduino Mega by HiLetgo. The enclosure is less enclosed than some others, comprising two sheets of acrylic (with cutouts for access) screwed together in the corners. This leaves the sides of the board fully exposed, which is handy for port access but not as protective.

Unusually, it’s sold in a pack of five, but if you’re planning several projects that could be exactly what you need!

• Price: ~$10 for five
• Features: Clear acrylic enclosure, open sides for port access
