The easy-to-use controller allows designers to scale industrial automation projects using the open Arduino ecosystem. The Opta PLC supports real-time control, monitoring, and predictive maintenance, making it an ideal choice for IIoT and building automation applications.
The Arduino Opta micro PLC is based on the STM32H747XI dual-core microcontroller from STMicroelectronics, which includes a single high-performance Arm Cortex-M7 core running at up to 480MHz and a lower-power Cortex-M4 core running at up to 240MHz alongside a shared floating-point unit.
The Opta is offered in three variants:
• Opta Lite, which includes Ethernet connectivity and USB Type-C for programming
• Opta RS485, which adds RS485 half-duplex support
• Opta Wi-Fi, which includes radios for Wi-Fi and Bluetooth Low Energy connectivity
All models support over-the-air updates and feature a dedicated secure element for cryptographic assurances, plus relays for switching four loads of up to 2.3kW each. The highly versatile controllers also include optional support for standard IEC 61131-3 PLC languages and fieldbus integration via Modbus TCP and Modbus RTU.
The Opta PLCs were recently featured in a Mouser webinar. Featuring two expert panellists from Arduino, the video webinar provides device designers with everything they need to know to develop and scale their industrial automation projects.
