Description
Arduino Opta Series – Secure Dual-Core PLCs for IoT & Automation
The Arduino Opta Family is a robust and secure range of micro Programmable Logic Controllers (PLCs) designed for industrial IoT, building automation, and energy management. Developed in partnership with Finder® and powered by the STM32H747XI dual-core Cortex-M7/M4 processor, the Opta family offers advanced real-time control, predictive maintenance, and seamless connectivity options.
Ideal for professionals scaling industrial automation projects, the Opta devices support both Arduino and IEC-61131-3 PLC programming languages, ensuring flexibility and ease of integration.
Family Highlights:
-
Powerful dual-core STM32H747 microcontroller
-
8 configurable analog/digital inputs and 4 high-power relay outputs (10A each)
-
Secure hardware encryption with onboard ATECC608B secure element
-
Programming in Arduino IDE and PLC languages (LD, FBD, ST, SFC, IL)
-
Ethernet and USB-C connectivity with OTA firmware update support
-
Industrial certification and DIN rail mounting for professional installations
