## Overview

The Arduino Opta Lite is a compact, industrial-grade micro PLC featuring a powerful dual-core STM32H747XI MCU, designed for real-time control and predictive maintenance. It ensures robust security with onboard secure elements and X.509 compliance, supports OTA updates, and offers versatile programming options including Arduino sketches and standard PLC languages. With multiple connectivity options and seamless integration with Arduino Cloud, it empowers professionals to scale automation projects efficiently within a durable black alloy steel chassis.

## Description

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.

Review: I have programmed many small PLCs in my time, but this is the worst ever. Inadequate software from arduino and a vastly over engineered connection method. I will stick with Siemens Logo DO NOT buy this OPTA at the moment, perhaps in later years when the interfaces and connection methods are much improved but certainly not at the moment.
Review: La pecca di questo prodotto è il software Arduino PLC IDE, ancora da finire di sviluppare direi. Lato hardware peccato non ci siano i LED abbinati agli ingressi!! Altrimenti 5 stelle ci stavano!

### ⭐ Review
*by K***R on 30 July 2025*

I purchased the Opta Lite with hopes it would be a solid / user friendly product that can be used for small projects and to help teach others who want to use it for basic PLC operation and programming to get beginners into automation. I was unfortunately severly disappointed. There are two IDEs that are used to operate the device from Arduino - Arduino IDE and Arduino PLC IDE. In order to get to where you can actually use the PLC for it's intended purpose by using the typical programming languages to build it's functions, you have to start by connecting to the PLC. This is a significant issue that I have yet to solve. The documentation leaves out important information for setting up communication and does not provide good troubleshooting steps to connect. Without thorough and complete documentation or customer support, this product doesn't do the bare minimum of bringing the customer to the basic setup of its logic. Perhaps this product was released too soon before working out bugs or before adequate documentation could be completed, but either way it was a complete waste of $150 and would serve better as a paperweight. When I tried to reach out to Arduino to get support, the only page that allowed contact info to be filled out would not actually allow me to click on the boxes or fill them out (I tried multiple browsers and even mobile). Support is clearly behind the curve for Arduino. I hope Arduino can solve its issues instead of continuing to market an unusable product.
