Description

Arduino Opta is a secure and easy-to-use micro PLC with Industrial IoT capabilities.

Developed in partnership with Finder – a leader in industrial and building automation – 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), this device was designed specifically for PLC engineers.

Its powerful STM32H747XI dual-core Cortex®-M7 + M4 processor enables users to perform real-time control, monitoring, and implement predictive maintenance applications.

Secure and durable by design, Opta supports OTA firmware updates and ensures data security from hardware to the Cloud thanks to the onboard secure element and X.509 Standard compliance. Additionally, the device undergoes regular assessments to maintain and improve its cybersecurity posture.

All of this is complemented by the ease of deployment in production, characteristic of Arduino Pro, thanks to a vast range of readily available software libraries and Arduino Sketches.

Last but not least, various connectivity options make system management effortless via real-time dashboards integrated with Arduino Cloud or third-party services.

Opta comes in three variants, so you can choose the best option for your project. Opta Lite is the most agile version, featuring onboard Ethernet and USB-C programming ports.
