The M-Duino Ethernet PLC Arduino 21 w/ GPRS is a sophisticated automation solution designed for professional environments. This modular controller integrates a variety of industrial communication protocols including I2C, RS232, RS485, and SPI, ensuring versatile connectivity options. It features multiple analog and opto-isolated digital inputs and outputs, providing robust control capabilities for a wide range of applications.
The PLC is equipped with LoRa connectivity, a long-range wireless modulation technology known for its high interference tolerance and low power consumption. LoRa is particularly suitable for IoT networks and applications where long-distance communication is required, such as smart cities and agricultural monitoring. The technology operates on low-frequency ISM bands, offering point-to-point connections with extended range and low data transfer rates.
Additionally, the PLC supports DALI, a communication protocol for lighting control that allows bidirectional communication with connected devices. This protocol is ideal for managing large lighting systems, offering energy savings and reduced maintenance costs through automated control. It can handle up to 64 devices, providing professional control over various lighting configurations.
For remote monitoring and control, the PLC includes GSM/GPRS connectivity, enabling the transmission of text messages (SMS) with static or dynamic content to predefined phone numbers. This feature is particularly useful for installations requiring important information to be sent to a supervision center.
The integration of WiFi and BLE technologies allows for secure, high-speed wireless communications with a wide range of digital devices, facilitating internet access and data exchange without the need for cables. The M-Duino family incorporates the ESP32 WiFi/Bluetooth module, enhancing the PLC's wireless capabilities.
This Arduino-based (Open Source Hardware) PLC is designed for seamless integration into industrial settings. It offers the possibility to expand with additional I2C modules, allowing for extensive control of a vast number of inputs and outputs. The PLC can be programmed using the Arduino IDE platform, providing ease of use for coding and instant connectivity for programming, maintenance, and control through USB and Ethernet ports.
Please note that this product is designed for professional use and should be handled with care. It is important to adhere to all operational guidelines to ensure safe and effective use.

- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
