The Arduino Opta micro PLC, now available from Mouser, is based on STMicroelectronics' STM32H747XI dual-core microcontroller, which includes a high-performance Arm® Cortex®-M7 core running at up to 480 MHz and a low-power Cortex-M4 core running at up to 240 MHz, along with a shared floating-point unit (FPU).
The Opta is sold in three variants:
• Opta Lite, which includes Ethernet and USB Type-C™ connectivity for programming
• Opta RS485, which incorporates half-duplex RS485 compatibility
• Opta WiFi, which includes radios for Wi-Fi® and Bluetooth® Low Energy (BLE) connectivity
All models support over-the-air updates and include a dedicated secure element for cryptographic guarantees, as well as relays for switching four loads of up to 2.3 kW each. These highly versatile controllers also offer optional support for IEC 61131-3 PLC programming languages and fieldbus integration via Modbus TCP and Modbus RTU.
Opta PLCs were recently featured in a Mouser webinar. With two expert Arduino speakers, the webinar provides device designers with everything they need to know to develop and scale their industrial automation projects.
