Arduino Opta, specially designed for PLC engineers, is a secure, easy-to-use micro PLC (Programmable Logic Controller) with industrial IoT capabilities.

Opta is equipped with frequently used networks and protocols in multiple industries, and supports both Arduino sketch and standard PLC languages, including LD (Ladder Logic Diagram) and FBD (Function Block Diagram). And its powerful STM32H747XI dual-core Cortex®-M7 +M4 MCU allows users to perform real-time control, monitoring, and implement predictive maintenance applications.

Secure and durable by design, Opta supports OTA firmware updates and ensures data security from the hardware to the Cloud thanks to the onboard secure element and X.509 standard compliance. Meanwhile, it maintains Arduino Pro's signature easy deployment in production thanks to a vast range of readily available software libraries and Arduino sketches. Last but not least, various connectivity options make keeping everything under control effortless via real-time dashboards combined with intuitive Arduino Cloud (or third-party services). Users can update wireless firmware and achieve remote control easily.

Product Overview of Arduino Opta WiFi Micro PLC

Figure 1: Product Image

Opta is mainly programmed on the Arduino PLC IDE, which makes PLC programming easy. Choose any of the 5 programming languages defined by the IEC 61131-3 standard (Ladder, Functional Block Diagram, Structured Text, Sequential Function Chart, or Instruction List) and users can quickly code PLC applications or port existing ones to Arduino Opta.
