MOUSER ELECTRONICS Arduino’s Opta Micro Programmable Logic Controllers (PLC) is easy-to-use and 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 suitable for industrial Internet of Things (IoT) and building automation applications. The 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 (FPU).

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 WiFi, which includes radios for Wi-Fi® and Bluetooth® Low Energy (BLE) 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 2.3 kW each.
