Industrial Reliability Meets Open Source Flexibility

NEXTuino bridges the gap between the programming simplicity of Arduino and the hardware robustness demanded by industrial environments — without compromise.

Arduino IDE Compatible

Program your industrial controller with the Arduino IDE you already know. Full compatibility with the Wiring language, libraries, and the open-source ecosystem — zero proprietary toolchain required.

Industrial-Grade Hardware

Designed for the plant floor: wide supply voltage range, isolated I/Os, DIN rail mounting, and an extended operating temperature of −25 °C to +70 °C. Built to last in harsh environments.

Open Source Ecosystem

No vendor lock-in. Full hardware schematics, open firmware, and access to thousands of community libraries. Customize every layer of your stack — from hardware to application code.

Drop-In for Any Panel

Standard 35 mm DIN rail form factor, industrial screw-terminal connectors, and compact dimensions. NEXTuino fits straight into your existing electrical panels with no special enclosures needed.

Choose Your Controller

From entry-level automation to the most demanding industrial applications — the NEXTuino family scales with your project.

Built for the Plant Floor

Every NEXTuino controller is engineered for real industrial environments — not just lab conditions. Rugged construction, industrial-rated components, and tested compliance with industrial standards.

Wide Voltage Range

12–24 V DC input with reverse-polarity protection and transient suppression.

Frequently Asked Questions

Everything you need to know about NEXTuino industrial Arduino PLCs.

Yes. NEXTuino controllers are 100% compatible with the Arduino IDE and the Wiring programming language. You can install the NEXTuino board package via the Arduino Boards Manager in seconds. All standard Arduino libraries work without modification, and you can upload sketches over USB exactly as you would with any Arduino board.
NEXTuino accepts a wide input voltage range of 12–24 V DC, which is standard in industrial control panels. The power input includes reverse-polarity protection and transient voltage suppression. A standard industrial 24 V DC DIN rail power supply is the typical installation choice.
Absolutely. The full Arduino library ecosystem is available — over 5,000 libraries in the official Arduino Library Manager, plus any community library from GitHub. We also provide a dedicated NEXTuino library that exposes hardware-specific features like the onboard RTC, watchdog timer, and industrial I/O helpers with a clean, well-documented API.
Yes. NEXTuino is designed specifically for industrial use: the operating temperature range is −25 °C to +70 °C, digital inputs are optocoupled for noise immunity, relay outputs are rated for industrial loads, and all models mount on standard 35 mm DIN rail. The PCB uses industrial-grade components rated for extended service life.
Yes. All NEXTuino models include an onboard RS-485 transceiver for Modbus RTU communication — the de facto standard protocol in industrial automation. Higher-end models additionally support CAN bus and Ethernet (Modbus TCP). The NEXTuino Arduino library includes a ready-to-use Modbus stack.
NEXTuino controllers are designed to meet CE marking requirements for industrial electrical equipment. Full compliance documentation, including Declaration of Conformity, is available for download. Contact us if you require specific certification information for your application or region.
Yes — NEXTuino is specifically designed for OEM integration. We offer volume pricing programs, long-term availability commitments, and application engineering support. Contact our sales team to discuss your production requirements and we will tailor a solution for your product line.
NEXTuino and Controllino share the same fundamental approach: Arduino-compatible PLCs for industrial use. NEXTuino differentiates through a broader product family spanning from entry-level to flagship performance, a more open hardware philosophy, and competitive pricing — particularly attractive for OEM volume applications. Both products are excellent choices for Arduino-based industrial automation.
