This Arduino Uno & Mega case is stackable, modular, extensible and hackable

It fits both Uno/Leonardo AND Mega footprints, and can accommodate any boards that have an Arduino footprint like SparkFun RedBoard, BlackBoard Artemis, etc. (see list of compatible devices below)

The case has an internal clearance of over 1.2 inches, which gives you ample room to install a shield (or two) of your choice!

Extension kits and add-ons are available to add functionality to your enclosure - add , switches, ultrasonic sensor, DB9/RS232 port, micro-servo and more! Check out our extension kits and add-ons!


  • Fits both Uno/Leonardo AND Mega footprints!
  • Internal clearance of over 1.2 inches, which gives you ample room for a shield (or even two!)
  • Made from high quality cast acrylic
  • Clear acrylic provides a beautiful finish with a modern visual design with full view of your electronics
  • Our Obsidian black acrylic gives you a sleek and attractive option when you want to keep your brains and sinew under the covers and just highlight the peripherals
  • Pre-drilled and threaded mounting holes in the base plate allow you to directly screw the board in without needing additional nuts, making it very easy and elegant for you to use. A thoughtful feature that you will surely appreciate if you have larger hands and dealing with tiny M2.5 nuts!  
  • Acrylic risers raise your board off the base plate for improved airflow and firm level mounting
  • Metal standoffs and screws provide solid and durable support 
  • Rubber Feet protect your table surface while providing maximum airflow by elevating the enclosure
  • Cutouts leave USB and power ports accessible 
  • Cable Management: Easily accessible cable management cutouts in the side walls allow you to smoothly insert your cables and access wiring to external systems. In the Open Configuration, the Wall slots on the top and bottom plates (where the side walls usually insert into) can also be used for cable management for even more accessibility and organization.
  • You can mix, match, customize, and expand your project enclosure because ProtoStax enclosures are modular and stackable and work with each other. 
  • Extension kits and add-ons help add functionality to your enclosure, such as adding switches, displays, sensor peripherals, etc.

ProtoStax Enclosures are Stackable, Modular & Extensible

ProtoStax eases your path from Prototype to Product. Go from a jumble of wires and boards to an attractive product you can proudly display on your coffee table, carry around, share with friends and family, or even sell to customers! Make your prototypes useable and attractive with ProtoStax!

  • ProtoStax Enclosure / Case in Platform Configuration showing Arduino. Pre-drilled and threaded mounting holes make assembly easy and convenient. Acrylic risers elevate board off the surface for improved airflow

    Use it as a prototyping plate, with full and open access to your device while prototyping. Rubber feet protect your board and your table top! 

  • ProtoStax Enclosure / Case in Open Configuration showing Arduino

    Omit the side walls and just add the top for an open configuration with more airflow and open access. 

  • ProtoStax Enclosure / Case in Fully Closed Configuration showing Arduino

    Add side walls and the top to form a fully enclosed case for maximum protection. 

    The cases offer connectivity to external systems using our unique cable management methods (see features above)


Extension kits and Add-Ons allow you to add functionality to your enclosure. Add a fan or two, switches, camera & tripod mount, and more! Thanks to our modular design, you can simply swap out existing pieces with new pieces that offer additional functionality like displays, switches, fans, cameras, tripod mounts are more.

All ProtoStax cases are compatible with each other and can be stacked side-by-side (horizontally) or one on top of the other (vertically). Mix-and-match multiple ProtoStax cases and put together a larger enclosure from the individual ones! Our Raspberry Pi + Breadboard, or Arduino + Breadboard enclosures are popular bundles, allowing to include more breadboarded circuitry while still making your prototype attractive and usable. Our stacking features and interoperability between enclosures means you can create your ultimate hybrid Raspberry Pi cluster/tower, mix-and-matching various Raspberry Pi A+, B/B+, Zero boards as you see fit!
