DESCRIPTION
Arduino Opta is a compact, secure micro PLC designed for Industrial IoT applications, combining ease of use with powerful control capabilities.
Developed in collaboration with Finder, a leader in industrial and building automation, Opta enables engineers to scale automation systems with the reliability of standard PLC languages and the flexibility of Arduino programming.
At its core, a robust STM32H747XI dual-core Arm® Cortex®-M7+M4 MCU powers real time operations, data monitoring, and predictive maintenance tasks. Built with security and durability in mind, it includes OTA update support and embedded secure element technology to protect data from edge to cloud, fully compliant with X.509 standards. Like all Arduino Pro solutions, it ensures a smooth transition to production through access to extensive software libraries and example sketches. With multiple connectivity options and integration with Arduino Cloud or third-party platforms, Opta simplifies remote management through real time dashboards.
Program Arduino Opta or Portenta Machine Control effortlessly with the Arduino PLC IDE.
Take advantage of IEC 61131-3 standard languages Ladder, Function Block Diagram, Structured Text, Sequential Function Chart, or Instruction List to create PLC logic or migrate existing code with ease.
