Overview
Arduino Opta is a secure, easy-to-use micro PLC with Industrial IoT capabilities.
Designed in partnership with Finder – leading industrial and building automation device manufacturer – Opta allows professionals to scale up automation projects while leveraging the Arduino ecosystem. Supporting both Arduino sketch and standard PLC languages, including LD (Ladder Logic Diagram) and FBD (Function Block Diagram), it was designed with PLC engineers in mind.
Its powerful STM32H747XI dual-core Cortex®-M7 +M4 MCU allows users to perform real-time control, monitoring and implement predictive maintenance applications.
Secure and durable by design, it supports OTA firmware updates and ensures data security from the hardware to the Cloud thanks to the onboard secure element and X.509 Standard compliance. In addition, Opta undergoes regular assessments to uphold and improve its cybersecurity posture.
All while maintaining Arduino Pro’s signature easy deployment in production thanks to a vast range of readily available software libraries and Arduino sketches.
Last but not least, various connectivity options make keeping everything under control effortless via real-time dashboards combined with the intuitive Arduino Cloud (or third-party services).
Opta comes in three variants so you can choose the best option for your project. Opta RS485 features Ethernet onboard and USB-C programming ports and RS485 half duplex connectivity interface.
Need Wi-Fi/Bluetooth® Low Energy connectivity? Opta WiFi is the best variant for you.
Happy with just Ethernet and USB-C? Check out Opta Lite.
Program it with the Arduino PLC IDE!
The Arduino PLC IDE makes PLC programming easy. Choose any of the 5 programming languages defined by the IEC 61131-3 standard (Ladder, Functional Block Diagram, Structured Text, Sequential Function Chart or Instruction List) and quickly code PLC applications or port existing ones to Arduino Opta.
Key benefits include:
- Easy and fast software development, starting from ready-to-use Arduino sketches, tutorials and libraries
- Support for standard IEC 61131-3 PLC languages
- Fieldbus integration via Modbus TCP (ethernet) and Modbus RTU (serial RS485)
- Real-time remote monitoring via intuitive Arduino Cloud dashboards (or third-party services)
- Security at the hardware level thanks to onboard secure element and X.509 Standard compliance
- Secure OTA firmware updates and Cloud device management
- High-power relay switching (4 x 2.3 kW)
- Reliable by design, thanks to industrial certifications and Finder’s expertise in switching technology
- Easy to install, with DIN rail compatibility
Opt in to industrial automation
Integrate a solid and reliable micro PLC with your existing machines, devices and production lines – also in combination with other elements in the modular and versatile Arduino ecosystem, from small and smart sensor-packed modules to SOMs to gateways, for end-to-end solutions that can be customized to meet any need.
Quality by design
Arduino Pro partnered with Finder, a leader in the field of electromechanical and electronic components with 65+ years of excellence and expertise to its name, to create a product with high-quality production specs for even the most demanding work conditions in industrial environments.

Weather forecast for 7 days and current (local) weather data displayer using the Arduino Opla IoT Kit
We’re excited to announce the launch of the Arduino Oplà Kit, the first open programmable IoT platform that allows you to add smart connectivity to the devices around your home or workplace and build custom IoT devices. The Oplà IoT Kit contains all the hardware necessary to create eight connected applications, access to an online platform with assembly instructions, and a 12-month subscription to the Arduino Create Maker Plan. This kit is perfect for beginners with basic DIY experience, while more advanced users can leverage it to customize and hack their smart applications and devices, with full control of their data and processes. Eight out-of-the-box projects to connect your home or workplace The projects included in the Oplà IoT Kit enable users to turn everyday appliances into smart appliances, which can be controlled remotely on a mobile phone: Remote Controlled Lights — Change color, light modes, and switch on/offPersonal Weather Station — Record and monitor local weather conditionsHome Security Alarm — Detect motion and trigger warningsSolar System Tracker — Retrieve data from planets and moons in the solar systemInventory Control — Track goods in and outSmart Garden — Monitor and manage the environment for your plantsThermostat Control — Smart control for heating and cooling systemsThinking About You — Send messages between the kit and the Arduino IoT Cloud Create, connect, control. The Internet of Things has never been so easy! No soldering is required with the Oplà IoT Kit, which is based on a MKR IoT carrier with an OLED color display, on-board environmental sensors, and capacitive touch buttons. The kit also includes a MKR WiFi 1010 board, a circular plastic enclosure and supporting accessories, such as two cables, a motion sensor, a moisture sensor, and a USB cable. To build applications, users can rely on the Oplà online platform. Each project includes goals, an intro to the components,
