What an incredible week it was! If you joined us at Embedded World 2025 in Nuremberg, Germany, you already know it was a standout year for the Zephyr Project. Despite flight delays and cancellations, we still made it—and so did the community. If you missed it—don’t worry. The Zephyr team is heading to Embedded World China and North America later this year, and we can’t wait to meet even more of you across the globe!
A Bigger Booth, A Bigger Community
This year, the Zephyr Project expanded its presence at Embedded World with a larger booth in Hall 4 (Booth 170), more participating member companies, and a greater number of interactive demos and real-world products powered by Zephyr RTOS.
From smart wearables to industrial automation, automotive to medical devices, we had real-world products on display, giving visitors a firsthand look at where and how Zephyr is making an impact. (If you would like to get your product listed on the Zephyr project website, fill this form.) Our interactive displays and engaging member demos offered a firsthand look at what’s possible with Zephyr.

Great Conversations
We had tons of engaging conversations with developers, engineers, and industry leaders. Some of the most popular questions we heard were:
- “How do I get started with Zephyr RTOS?”
- “Where can I learn more about Zephyr RTOS?”
- “How to migrate from my current RTOS to Zephyr RTOS?”
- “What about safety certification for medical and automotive use?”
Spoiler alert: Yes, Zephyr is moving fast in these areas, and we are committed to making it even easier to adopt. Check out this blog “What to Expect from the Zephyr Project in 2025” by Amy Occhialino – Intel Corporation, 2025 Governing Board Chair for the Zephyr Project for more information.
How many of you still have your reel board? If you stopped by the Zephyr project booth this year, you may have spotted the LUG-Nuremberg (Linux User Group) crew, led by Jürgen, proudly showcasing theirs!
From the very beginning of the Zephyr Project back in 2016, the LUG-Nuremberg team has been a regular presence at our booth. Their passion for open source and continued support for Zephyr has been inspiring—and their reel board badge is a reminder of how far we have come together.
We are always excited to see community veterans like LUG-Nuremberg who’ve been with us from the start, continuing to celebrate and contribute to the Zephyr Project ecosystem.
Booth Party 🎉
What’s a great event without a little fun? We hosted an evening after-booth party where developers, partners, and community members could relax, network, and continue the conversations in a more casual setting. It was a fantastic way to cap off an exciting day on the show floor.
Big thanks to the IRNAS team for bringing delicious regional wines and to the inovex team for the classic Nuremberg pretzels – local treats that made the evening even better.
See You at the Next Stop!
Embedded World 2025 in Germany was a milestone event for the Zephyr Project. We are excited to carry this momentum to China and North America next. Check out the next events from the Zephyr community here and come meet us – we would love to connect!
