And if you desire to plug in rockets and not-a-flamethrowers, please request from Mr. Musk. We're convinced he's got it in the bag.

Smart Gateway

PuzzleIoT is a computer that takes care of the local processing as well as near and far connectivity. The device runs on Android Things to guarantee you a well documented platform to build on.

Customizable Hardware

Use USB and Ethernet to plug in more devices and sensors or dive deeper and add components under the hood. Because PuzzleIoT is to be pre-certified the amount of engineering acrobats required to do so is significantly reduced.

Pretty cool, yea?

If you like what you see, let's talk more.

But, but, what can I build on it, you ask.

Funny you should ask, we have some ideas :)
Are you ready to build some bad ass demonstrators?
Engage! Arriba, arriba! Oooo, macarena!

The design ideology

The problem of hardware isn't on the component level. The world is working on components - engineers make progress daily. The problem is hardware architecture. Why are electronics designed for obsolescence? Is there a way for hardware architecture to be robust enough in order for it to sustain the progress of technology and user requirements?
We say, yes!

Fix when broken

Do you remember the time when we fixed electronics when they broke - swapped batteries and replaced worn out components? We remember those times too and want to bring them back. When electronics are designed well you can repair them instead of throwing them to a bottomless bin.

Upgrade as required

Are you ready for 6G? We are! Just plug it in and so are you. IoT ecosystems will have to absorb all of the technological advances we constantly make but also the increasing user requirements and security threats. You better be able to upgrade. Fast.


Electronics should serve your need. There is no reason why electronics are only to be bought off the shelf and used as they are. Better yet, electronics product development shouldn't have the high hurdles it currently has. Creating bespoke electronics on top of pre-certified robust electronics architecture is faster, cheaper, and lowers the associated risks.

Save the mother ducking nature

Enough with the mindless wasting of the planet's valuable resources. We can do better than this. Can you imagine what will happen geopolitically when the critical raw (earth) materials demand is only ever increasing globally? The only way to sustainably retain the value of these critical raw materials is keep the devices working longer. Let's do this!

Designing robust architecture, modularity

As far as we can see the above rant leads us to one solution, modularity. Modularity is a way to silo a device into compartments that can be upgraded, reengineered, or replaced individually. And when those silos are pre-certified engineering additional electronics in is a no brainer.

The critical barrier for modularity is standardized connectivity between the modules. This connectivity has to withstand the wear and tear of the type of use that monolith devices don't. Further, the connectors must be able to conway the signals from one module to the other. This is why we have spent a lot of time and resources in creating connector solution that would be the best compromise and optimal for long term use. Patent is now pending.

We do this because both you and the world deserve better devices

Turn PuzzleIoT into what you need your edge to be. We have taken care of the basics, building on it is a breeze.

The Mother Ship - Circular Devices Oy

PuzzleIoT is a product of Circular Devices Ltd. We specialize in electronics architecture innovation. You can call us an electronics design house. Currently we are developing a modular smartphone, PuzzlePhone, and PuzzleIoT is very conveniently along the roadmap as the smartphones have everything a great IoT device can have. We just add a bit of IoT specific components in and look into user journeys in IoT. Formfactor is different from smartphone but much of the electronics are the same.

We are excited to finally have products in our hands. This journey has taken way longer than expected but since we have secured enough funds to get to the IoT device we have tried to stay patient. We know a lot of you out there have been expecting news from us. We’re sorry it has taken this long. You, sincerely, have been in our minds daily even when our hands and resources have been tied to R&D. We'll keep pushing forward in order to make a difference - to make things right. Stay tuned and much love to all.
