Description
Modular FADUINO is an Arduino-compatible industrial controller built for industrial automation applications. Based on the familiar Arduino ecosystem, it keeps development approachable while providing the reliability, wiring practicality, and stability expected in industrial environments.
The key advantage of Modular FADUINO is its modular architecture. By combining a CPU base with interchangeable I/O and function modules, users can configure a system that matches the exact requirements of each machine or control panel. This allows flexible expansion, easier maintenance, and faster customization compared to fixed I/O controllers.
With PLC-like functionality and multiple industrial communication interfaces, Modular FADUINO integrates smoothly into automation systems. It is designed for stable long-term operation, even in demanding field conditions, making it a strong choice for prototyping-to-production workflows.

FAQ
Q: What development tools are used?
A: We use the Arduino IDE. You can develop in the same environment as standard Arduino projects, making it easy and familiar to get started.
Q: Can’t I just use a regular Arduino? Why should I use FADUINO?
A: For hobby or educational projects, a standard Arduino is perfectly fine. However, industrial environments are a different story. In the field, electrical noise, surges, and interference are always present. Without proper hardware-level protection, machines are likely to suffer from repeated malfunctions and failures.
These issues cannot be solved by software alone—they require robust industrial-grade hardware design, which is why FADUINO is the better choice for industrial applications.
Q: The concept of “moduler” is unfamiliar. How does it work?
A: This concept may feel unfamiliar because it does not exist in standard Arduino systems. In industrial environments, it is common to design systems with future expansion in mind or to add more I/O when the predefined I/O is insufficient, as field requirements often change. To address this, the system adopts a modular I/O approach, allowing required I/O to be connected as modules.
Since we provide the necessary libraries, using these modules should not be difficult.
