Arduino Opta WiFi Micro PLC 12-24VDC (Ethernet, RS485, Wi-Fi & BLE) | Najoom Al Falah KSA
The Ultimate Wireless Solution for Industrial IoT (IIoT) The Arduino Opta WiFi (AFX00002) is the most advanced model in the Opta micro PLC lineup, delivering unparalleled wireless connectivity for modern industrial automation. Co-designed with automation experts Finder, this programmable logic controller perfectly bridges the gap between the flexible Arduino ecosystem and demanding industrial environments. By integrating onboard Wi-Fi (802.11 b/g/n) and Bluetooth® Low Energy (BLE) alongside standard Ethernet and an RS485 port, the Opta WiFi enables seamless, over-the-air monitoring and control without the need for complex network cabling. Driven by the robust STM32H747XI dual-core processor, it easily handles real-time control, data logging, and predictive maintenance. Automation engineers can rapidly deploy logic using standard IEC 61131-3 PLC languages (such as Ladder and FBD) via the Arduino PLC IDE. Equipped with a dedicated ATECC608B hardware crypto chip, it guarantees secure boot, secure Over-The-Air (OTA) firmware updates, and safe data transmission to the Arduino Cloud or third-party dashboards.
