The Arduino Opta® is a secure, easy-to-use micro PLC with Industrial IoT capabilities. Designed in partnership with Finder®, a leading industrial and building automation device manufacturer.
Thanks to its computing power, Arduino Opta® enables a wide range of real-time control, monitoring and predictive maintenance applications.
It allows professionals to scale up automation projects while taking advantage of the open and widely known Arduino ecosystem.
Quickly put it to work, leveraging the many available software libraries. The onboard secure element ensures Over-The-Air firmware updates and remote control via the Arduino Cloud or third-party services.
Arduino Opta® is available in three variants:
- Arduino Opta® Lite: on-board Ethernet and USB-C® ports
- Arduino Opta® RS485: on-board Ethernet and USB-C® ports, plus RS-485 connectivity
- Arduino Opta® WiFi: on-board Ethernet and USB-C® ports, plus RS-485 and Wi-Fi®/Bluetooth® Low Energy
H7's main processor is the dual core STM32H747 including a Cortex® M7 running at 480 MHz and a Cortex® M4 running at 240 MHz. The two cores communicate via a Remote Procedure Call mechanism that allows calling functions on the other processor seamlessly.
Multiple choices are available for network connectivity, including USB, Ethernet, and Wi-Fi®/Bluetooth® Low Energy in addition to industry specific protocols such as RS-485.
Arduino Opta® has a highly reliable design operating at industrial temperature ranges (-20 °C to +50 °C) thanks to a dual-core architecture that doesn’t require any external cooling.
