U-PHY at a glance

U-Phy is a pre-certified fieldbus firmware, running on open hardware designs. Our most common communication protocols are built-in from the start. All you need is there. Only one single and unified API for all fieldbuses is needed.

A software driven approach to industrial communication.

Cuts your costs. No royalties or run time fees.

Built in data analysis for real-time network data monitoring.

No proprietary hardware needed. Runs on open hardware design.

Evaluation kit

The evaluation kit is an easy way to get started with U-Phy. It comes with everything needed to get started – Module 01, Arduino shield, USB cable and a manual.

Open design hardware

Your own design or our prefab design, the choice is yours.
You can buy and use our prefab hardware to jumpstart a project or integrate its schematic completely.

The hardware schematics are free to download and use.

Talk TO any fieldbus

Make your product global. Get all fieldbuses at once.


Deploying U-Phy in your project is easy and straight forward. U-Phy reduces the integration time by more than 60% in comparison to traditional fieldbus solutions.


Our Arduino 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 know that sometimes the project is in a rush and needed the solution yesterday. No problem, we got your back. By offering pre build, industrial grade and open design hardware modules that you can snap in and get your communication up and running in no time. Later on, when cost is your main driver, you can easily switch out the hardware module to a fully integrated solution right on your PCB.

Following our API implementation design guides is easy and gives your application full fieldbus access in no time.


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.


The U-Phy API is the only point of communication your product needs to access in order to communicate on the industrial network. It is literally one API for all communication protocols. Read more about the API here.

U-Phy has an extensive manual that describes how the API is interfaced and how you configure U-Phy for your product.

We provide comprehensive documentation, mechanical drawings, 3D models, and reference designs to help you build your perfect product.
