Arduino Opta targets Industrial IoT


Developed in partnership with Finder – a manufacturer of industrial and building automation devices – it is aimed at professional developers who want to take advantage of the wider Arduino ecosystem.

It is based on dual-core Cortex-M7 +M4 MCU for real-time control. , monitoring and maintenance programs. It supports OTA firmware updates with built-in security and X.509 compatibility, and there are real-time dashboards supported via Arduino Cloud or third-party services.

Features for Industrial IoT include:


  • Additional support for standard IEC 61131-3 PLC “languages” (Flow diagrams, functional block diagrams, structured text, sequential
  • function diagrams and instruction lists)
  • Fieldbus integration via Modbus TCP (ethernet) and Modbus RTU (serial RS485)
  • Internet of Things via Ethernet/Wi-Fi/Bluetooth® Low Energy
  • High power relay switching (4 x 2.3 kW)
  • Compatible with DIN rail
  • < /ul>

    There are three options: €122 for the Opta Lite (with built-in Ethernet and USB-C programming ports), €134 for the Opta RS485 (adding half-duplex RS485 connectivity) and €161 for the Opta WiFi (also with Wi-Fi/Bluetooth Low Energy).
