We believe hardware
should be open.

Open to inspect, open to modify, open to build upon — and open to the communities of makers, engineers, and developers who push automation forward.

NEXTuino industrial Arduino-compatible PLC
NEXTuino CREST — flagship industrial PLC

Industrial-grade. Genuinely open.

That belief is at the core of everything we make at NEXTuino. We design industrial-grade controllers that are 100% compatible with the Arduino ecosystem — same familiar programming environment, same libraries, same IDE you already know.

No proprietary lock-in. No walled garden. Just powerful hardware you can actually understand and extend.

Our products are built for demanding industrial environments — reliable under voltage spikes, temperature swings, and the kind of continuous operation that separates real automation hardware from hobby boards. Designed and manufactured to strict industrial quality standards, NEXTuino controllers bring together the robustness that plant floors require and the openness that developers deserve.

Because we think those two things should never have been mutually exclusive.

100% Arduino
compatible

Same IDE, same libraries, same workflow. No retraining. No rewriting.

Industrial
reliability

Built for 24/7 operation, voltage spikes, and the factory floor.

No
lock-in

Open schematics, documented pinouts, community-first design philosophy.

Community
driven

We grow alongside the open source ecosystem we are proud to be part of.

"Arduino-compatible" — not just a label.

It means you program NEXTuino exactly as you'd program any Arduino board — in the Arduino IDE, with standard libraries, with the same setup() and loop() structure you learned on day one.

Switching to NEXTuino doesn't mean retraining your team or rewriting your codebase. It means getting industrial I/O, real-time reliability, and a hardened enclosure without leaving the ecosystem you already trust.

NEXTuino RISE — Arduino-compatible industrial PLC

Open source hardware,
seriously.

We're committed to the open source hardware philosophy not as a marketing line, but as a design principle.

  • Schematics available
  • Pinouts documented
  • Community contributions welcome

We grow alongside the ecosystem we're part of.
