A Faster Path From Prototype to Product

You built the prototype. Now what?

Your project works — but turning it into something you can actually use, demonstrate and keep building on can be hard.

ProtoStax is a modular enclosure system that grows with your project — from your first prototype to a polished, professional-looking creation.

Every Maker Knows This Feeling

Your prototype finally works.

It's sitting on your bench, surrounded by jumper wires, a breadboard and loose components.

You know you'd like to turn it into something you can actually use, demonstrate and keep building on.

But turning it into a finished project usually means learning CAD, designing an enclosure, 3D printing, laser cutting, or modifying project boxes. Suddenly, packaging the project can take as much effort as building it.

For many makers, that's where great ideas end.

ProtoStax removes the barrier between a working prototype and a finished project, so you can spend less time figuring out how to package your project — and more time building what's next.

What if your enclosure could evolve too?

Most enclosures are designed for finished projects.

ProtoStax is designed for projects that are still evolving.

  • Start with a platform. 
  • Add protection when you need it. 
  • Reconfigure as your project changes. 
  • Add functionality as it grows. 
  • Reuse for other projects later on.

Your project doesn't have to fit the enclosure. The enclosure adapts to the project.

Why ProtoStax?

Designed Around the Way Makers Actually Work

Projects evolve. Ideas change. Requirements grow.

ProtoStax began with a simple frustration:

“Why is it easier to build the electronics than it is to package them?”

Founder and Maker Sridhar Rajagopal kept running into the same problem: enclosures that fit one board too tightly, required cutting and drilling, or became obsolete as projects evolved.

That frustration led to a bigger question:

“Why doesn't the enclosure evolve with the project?”

The answer led to ProtoStax.

More than twenty design iterations, conversations with fellow makers, and countless refinements later, ProtoStax evolved into a modular platform designed to support the entire prototyping journey — not just the final step.

Today, that same maker-first philosophy guides everything we do: creating products and solutions that remove obstacles, adapt to the way makers work, and help turn ideas into reality.

One Platform. Every Stage of Your Project.

  • BUILD

    Bring your initial idea to life. Get your board and components working together on a stable prototyping platform that will evolve into the enclosure for your finished project.

  • DEVELOP

    Experiment, refine, and add functionality as your project takes shape.

  • DEPLOY

    Turn your working prototype into a project ready for everyday use or demonstration.

  • GROW

    Take your project further as new ideas and requirements emerge.

  • REUSE

    Sometimes projects come to an end. You can reconfigure and reuse your Enclosures, Extension Kits, and peripherals like cameras, buttons, and displays for your next project instead of starting from scratch. Repair, Reuse, Recycle, Upcycle – an ecofriendly approach that ProtoStax wholeheartedly supports! 😊♻️🌿🌍 

Your project changed. You don't have to start over.

START → ADD → EXPAND

Your projects evolve. ProtoStax lets you reconfigure, expand, and build on what you already have with modular components, stackable enclosures, and add-ons that grow with your ideas.

Swap in a display. Add buttons. Install cooling. Mount a camera. 

Mix and match Extension Kits and accessories to create exactly the system your project needs.

Stack multiple enclosures to make composite ones.

START: Three Configurations. One System →

  • Platform Configuration

    Mount your board and keep your electronics accessible. Rubber feet help protect your table or surface, keep your project from sliding around and elevate the board for better airflow.

  • Open Configuration

    Omit sidewalls for extra airflow, port access, or room for components.

  • Fully Closed Configuration

    Add sidewalls and a top for a more enclosed and polished setup, with room inside for a shield or HAT plus additional components.

ADD → EXPAND

  • ADD

    Add functionality. Keep building.

    Extension Kits and accessories make it easy to add functionality as your project evolves:

    ◆ Displays and buttons

    ◆ Fans and cooling

    ◆ Camera and sensor mounts

    ◆ Interchangeable panels and tops

  • EXPAND

    Think beyond a single enclosure.

    Stack and combine compatible ProtoStax enclosures to create larger systems, accommodate multiple boards, and build more complex projects.

    Finished ProtoStax enclosures can also be stacked for easy storage, with the rubber feet fitting neatly into the screw heads of the enclosure below. It's yet another thoughtful detail that makes ProtoStax practical at every stage of your project.

Thoughtful Details. Easier Building

Threaded mounting holes

Mount your board directly without additional nuts.

Acrylic risers

Keep boards elevated for airflow and a level mounting surface.

Removable rubber feet

Protect surfaces, prevent sliding, allow for different mounting and stacking arrangements.

Modular assembly

Assemble easily and modify individual panels when your project needs something different.

Make It Yours

Making is creative. Your enclosure should be, too.

Choose Crystal when you want to showcase the electronics inside. Choose Obsidian when you want a darker, more refined finish. 

Get creative! Personalize your ProtoStax with decorative tops—from laser-etched designs to a Blank Canvas ready for your own artwork.

Style it. Customize it. Share it.

Because every project tells a story.

  • Choose Crystal to showcase your electronics

  • Add a touch of refinement with Obsidian

  • Laser-etched decorative tops add personality to your creation

  • ProtoStax Decorative Tops - Periodic Table of the Elements (paintable Top Plate)

    Grab a brush and some acrylic paint. Fill in your own colors. We'll show you how! 😊

  • Paint your own artwork! If your art skills need a little help, recruit your child, niece or nephew, grandkid, or a creative friend to add a personal touch!

What Makers are saying

  • Very flexible and easy enclosure for Pi Zero

    I found this kit because I needed a bit of space inside my enclosure for other electronics, not just a Raspberry Pi Zero. It's very flexible and very easy to build. Just what I wanted.

    — Andrew Richards

  • Elegantly styled. Beautiful viewing window

    This is a very glamorous case with a giant view of the onboard display. Assembly is easy.

    — Claudius

  • Great products and service

    I was able to get everything I needed from ProtoStax to build my hybrid Rpi 5 case. Had questions and an issue with the parts I would need, they were extremely helpful and got me going. Would definitely recommend them to anyone, and will buy from them again.

    — Russ Harvey

  • Love ProtoStax!

    Wonderfully designed, durable product. I have used them for multiple projects over the years.

    — Pete

Choose Your Starting Point

Every ProtoStax enclosure shares the same philosophy:

Start simple. Expand naturally. Reuse often.

Choose the platform that's right for your project:

  • Raspberry Pi : For Pi B (3/4/5), Pi A+ and Pi Zero
  • Arduino : We have two solutions - one for Uno and Mega footprints, and one for the Arduino Giga Display
  • Breadboard & Custom : Ideal for breadboards, ESP32/Raspberry Pi Pico/Arduino Nano/Particle, custom PCBs, and unique electronics project
  • Extension Kits : Displays, buttons, cooling, cameras, mounts, and more

Everything works together. Everything grows together.

Level Up Your Prototype

You've already solved the hard part—you built something that works.

Now give your project a modular home that can evolve alongside it.

Whether you're building for your home, your classroom, a school project, your customers, or simply for the joy of making, ProtoStax helps you spend less time building enclosures and more time building what's next... 

Start Building with ProtoStax!
