Industrial-ready micro PLC with built-in Wi-Fi + IoT connectivity perfect for automation and smart control tasks.

1 Powerful Dual-Core MCU

• STM32H747XI dual-core ARM processor Cortex-M7 (up to 480 MHz) high-performance control and computation Cortex-M4 (up to 240 MHz) real-time peripheral handling

Enables real-time control, data processing, and protocol handling within the same controller.

2 Connectivity for IoT & Industrial Networks

• Wi-Fi 802.11 b/g/n wireless connectivity for remote access, dashboards, or cloud services.

• Bluetooth Low Energy (BLE) short-range device communication.

• Ethernet (Modbus TCP) wired industrial network support.

• RS-485 (Modbus RTU) fieldbus standard for industrial sensors and actuators.

This range of interfaces makes it suitable for factory automation, sensor networks, and building control systems.

3 I/O Capabilities

Inputs

• 8 configurable digital or analog (0-10 V) inputs read sensors, switches, process signals.

Outputs

• 4 mechanical relay outputs (up to 10 A @ 250 VAC) control pumps, lights, fans, actuators.

These make the Opta suitable for both sensing and actuation in automation panels and equipment.

4 Programming Flexibility

Arduino IDE support Eguages Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), Sequential Function Chart (SFC), and Instruction List (IL).

This lets both hobbyists and professional automation engineers use the same hardware and tools they prefer.

5 Industrial-Grade Security & Maintenance

• ATECC608B secure element with X.509 certificate support protects credentials and encrypted communication.

• Secure OTA firmware updates maintain devices remotely and safely.

These features are critical for secure IoT deployments in industrial settings.

6 Rugged, Reliable Design

DIN-rail compatible standardized industrial mounting. IP20 protection suitable for control panels and industrial enclosureson factory floors. CE, ENEC, cULus certifications safety and quality approvals.

7 Typical Use Cases

Industrial automation & PLC control Remote monitoring & IoT dashboards Building automation & lighting control Energy usage monitoring Smart factory sensors & actuators Predictive maintenance systems

It bridges the gap between Arduino ease-of-use and traditional PLC reliability.
