## Overview

The Arduino Opta Lite is a compact industrial IoT controller designed for space-constrained automation projects. Featuring 16 programmable voltage inputs, 8 digital inputs, and PWM outputs, it supports industry-standard Modbus RTU and TCP protocols for seamless integration. With built-in edge computing capabilities, it enables local data processing to reduce latency and ensure continuous operation. Fully compatible with the Arduino IDE, it empowers engineers and developers to rapidly prototype and deploy smart industrial control systems.

## 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: Terrible and over engineered connection method - 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.

## Features

- Compact and Powerful Industrial IoT Controller: The Arduino Opta Lite is a compact yet powerful industrial IoT controller, designed for space-constrained applications where performance and flexibility are critical. With a small footprint, it is ideal for deploying in tight spaces while providing ample I/O capacity to handle industrial automation, monitoring, and control systems.
- Comprehensive I/O for Versatile Applications: The Opta Lite features digital I/O, analog inputs, and PWM outputs, enabling seamless integration with a variety of sensors, actuators, and external devices. It’s perfect for applications such as environmental monitoring, remote control, machinery automation, and smart building systems.
- Modbus RTU & TCP Support for Industry Standard Protocols: The Opta Lite supports both Modbus RTU and Modbus TCP, widely used protocols for industrial communication. This makes it easy to integrate the Opta Lite into existing control systems, enabling it to communicate effectively with PLCs, industrial devices, and other automation equipment, ensuring compatibility in a range of automation environments.
- Edge Computing Capabilities for Local Processing: With edge computing capabilities, the Opta Lite can process data locally without needing to rely on the cloud or a central server. This enables faster decision-making, reduces latency, and ensures continued operation even when connectivity to a remote system is lost, making it ideal for mission-critical applications in automation and control systems.
- Arduino Ecosystem Integration for Easy Development: Like all Arduino boards, the Opta Lite is fully compatible with the Arduino IDE, allowing for easy programming and customization using familiar tools. Leverage the powerful Arduino ecosystem of libraries, resources, and community support to rapidly prototype and deploy industrial IoT solutions, making it an excellent choice for developers and engineers.
