just add hardware

The Module 01 is offered in two formats: first as a ready-to-use, prefabricated and pre-programmed module, and secondary as a free design asset included with the purchase of the Evaluation Kit. This gives you the possibility to completely integrate it into your own PCB, giving you with full control of your communication solution and also lowers your bill of materials significantly.

How it's done

1. Select hardware

U-Phy runs on open hardware designs – leaving you in control. Use one of our open reference designs or choose our prebuilt module 01.

2. MODEL your data

Model your communication – no protocol specific knowledge needed

3. Deploy your system

U-Phy is the most cost effective multiprotocol solution on the market.

Flexible Deployment Options

Every industrial automation project has its own set of unique challenges and requirements. That’s why we offer two convenient options to get you up and running with U-Phy.

1. Prefabbed module

Don’t want to spend time on hardware integration? Opt for our pre-fabricated hardware modules that come pre-flashed with U-Phy firmware. Just plug it in and you’re ready to go!

Purchasing our prefab Module 01 hardware is the quickest way to implement U-Phy into your industrial systems. It saves you the time and resources you’d spend on hardware design and firmware flashing.

2. RUN U-Phy on Your Own Hardware

If you prefer a hands-on approach or need a customized solution, you can purchase the U-Phy firmware only. This allows you the freedom to implement the hardware yourself based on your specific requirements.

We provide comprehensive hardware schematics to guide you through your implementation. This ensures that you have all the information you need to integrate U-Phy seamlessly.

U-Phy reduces the integration time by more than 60% in comparison to traditional fieldbus solutions.


Our Arduino header compatible evaluation kit makes evaluation easy. Create and model your fieldbus data using the supplied tools and that’s all there is to it, you are now ready.

INTEGRATE & Implement

We understand that sometimes projects are urgent, requiring immediate solutions. Don’t worry, we’ve got you covered. We offer pre-built, industrial-grade hardware modules with an open design that allows you to quickly establish communication. When cost becomes a primary concern, you can effortlessly transition from the hardware module to a fully integrated solution on your PCB.


Putting your product on the market sometimes requires the product to be certified through various organisations. With pre-certified products from RT-Labs and with the help from our guidelines, this process is a breeze.
