Overview

Arduino Opta is a secure, easy-to-use, compact PLC with Industrial IoT capabilities. Designed in partnership with Finder, the leading industrial and building automation device Manufacturer, Opta allows professionals to scale up automation projects while leveraging the Arduino ecosystem. It supports both Arduino sketch and standard PLC languages, including LD (Ladder Logic Diagram) and FBD (Function Block Diagram), for it was designed with PLC engineers in mind.

The powerful STM32H747XI dual-core Cortex®-M7 +M4 MCU allows users to perform real-time control, monitoring and implement predictive maintenance applications. Opta comes in three variants, so you can choose the best option for your project. Opta Lite is the most nimble and features Ethernet onboard and USB-C programming ports.

Opta RS485 features Ethernet onboard and USB-C programming ports and RS485 half duplex connectivity interface. Need Wi-Fi/Bluetooth® Low Energy connectivity? Opta WiFi is the best variant for you. Happy with just Ethernet and USB-C? Check out Opta Lite.
