Arduino Opta WiFi
Discover everything our most versatile Opta micro PLC has to offer: designed for engineers who need to keep their options open.
Overview
Arduino Opta is a secure, easy-to-use micro PLC with Industrial IoT capabilities.
Designed in partnership with Finder – leading industrial and building automation device manufacturer – Opta allows professionals to scale up automation projects while leveraging the Arduino ecosystem. Supporting both Arduino sketch and standard PLC languages, including LD (Ladder Logic Diagram) and FBD (Function Block Diagram), it was designed with PLC engineers in mind.
Its powerful STM32H747XI dual-core Cortex®-M7 +M4 MCU allows users to perform real-time control, monitoring and implement predictive maintenance applications.
Secure and durable by design, it supports OTA firmware updates and ensures data security from the hardware to the Cloud thanks to the onboard secure element and X.509 Standard compliance. In addition, Opta undergoes regular assessments to uphold and improve its cybersecurity posture.
All while maintaining Arduino Pro’s signature easy deployment in production thanks to a vast range of readily available software libraries and Arduino sketches.
Last but not least, various connectivity options make keeping everything under control effortless via real-time dashboards combined with the intuitive Arduino Cloud (or third-party services).
Opta comes in three variants so you can choose the best option for your project. Opta WiFi features Ethernet onboard and USB-C programming ports, RS485 half duplex connectivity interface, and Wi-Fi/Bluetooth® Low Energy connectivity.

Program it with the Arduino PLC IDE!
The Arduino PLC IDE makes PLC programming easy. Choose any of the 5 programming languages defined by the IEC 61131-3 standard (Ladder, Functional Block Diagram, Structured Text, Sequential Function Chart or Instruction List) and quickly code PLC applications or port existing ones to Arduino Opta.
Key benefits include:
- Easy and fast software development, starting from ready-to-use Arduino sketches, tutorials and libraries
- Support for standard IEC 61131-3 PLC languages
- Fieldbus integration via Modbus TCP (ethernet) and Modbus RTU (serial RS485)
- Seamless IoT connectivity (Ethernet/Wi-Fi/Bluetooth® Low Energy)
- Real-time remote monitoring via intuitive Arduino Cloud dashboards (or third-party services)
- Security at the hardware level thanks to onboard secure element and X.509 Standard compliance
- Secure OTA firmware updates and Cloud device management
- High-power relay switching (4 x 2.3 kW)
- Reliable by design, thanks to industrial certifications and Finder’s expertise in switching technology
- Easy to install, with DIN rail compatibility

I have prepare home Automoation project using Arduino nano esp32
There are almost endless variations of clocks for sale on the internet today, but it is still easy to end up in a situation where you can't quite find a model with the style and features you want. Marco Zonca ended up with that problem while searching for a new clock to put in his music studio. Nothing on the market fit the bill, so he built this minimalist network-updated digital clock. Zonca wanted a simple design, the ability to adjust brightness, and NTP (Network Time Protocol) updates. There are clocks available with those features, but nothing in the style Zonca wanted. So he created the perfect clock for himself. It displays 24-hour time across a red LED matrix, lets the user control settings like brightness via Bluetooth® Low Energy communication, and always stays in sync with network time. An Arduino Nano ESP32 board, programmed through Arduino Web Editor, controls all of those functions. It mounts onto a custom PCB that Zonca designed for this clock. The PCB also hosts an 8×32 LED matrix display with MAX7219 driver. Three buttons on the PCB let the user select modes. The PCB fits into a black 3D-printed enclosure that reflects the overall minimalist style. Now Zonca has the perfect clock for his music studio. If you like the look of it, the sketch, PCB files, and 3D enclosure are all available on Hackster.io.
