Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the Opta micro programmable logic controller (PLC) from Arduino. The easy-to-use controller 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 an ideal choice for industrial Internet of Things (IoT) and building automation applications.
The Arduino Opta micro PLC, now available at Mouser, is based on the STM32H747XI dual-core microcontroller from STMicroelectronics, which includes a single high-performance Arm Cortex-M7 core running at up to 480 MHz and a lower-power Cortex-M4 core running at up to 240 MHz alongside a shared floating-point unit (FPU).
The 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. The highly versatile controllers also include optional support for standard IEC 61131-3 PLC languages and fieldbus integration via Modbus TCP and Modbus RTU.
The Opta PLCs were recently featured in a Mouser Webinar. Featuring two expert panelists from Arduino, the video webinar provides device designers with everything they need to know to develop and scale their industrial automation projects.
