Opta-board

Opta

The Arduino Opta is a secure, easy-to-use micro PLC with Industrial IoT capabilities. Designed in partnership with Finder, 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:

  • Opta Lite: on-board Ethernet and USB-C® ports
  • Opta RS485: on-board Ethernet and USB-C® ports, plus RS485 connectivity
  • Opta WiFi: on-board Ethernet and USB-C® ports, plus RS485 and Wi-Fi/Bluetooth® Low Energy
Microcontroller
STM32H747XI dual Cortex®-M7+M4 32bit low power Arm® MCU

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.

WiFi and Bluetooth
Connectivity

Multiple choices are available for network connectivity, including USB, Ethernet, and Wi-Fi/BLE in addition to industry specific protocols such as RS485.

Temperature Sensor
Industrial temperature range

The 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.
