The Raspberry PLC 21 w/ RPi 4B (4GB) LoRa (EU) is an advanced industrial automation device that leverages the processing speed and power of Raspberry Pi technology. This modular PLC is designed for professional use and is equipped with a multitude of input and output options, including analog and digital optoisolated ports, to cater to a wide range of industrial applications.
The unit boasts robust industrial communication capabilities, featuring I2C, RS232, RS485, and SPI interfaces. It also incorporates LoRa connectivity, a long-range wireless modulation technology developed by Semtech and managed by the LoRa Alliance. LoRa is particularly known for its Chirp Spread Spectrum (CSS) modulation, which has been used in military operations for many years. This technology offers significant benefits, such as high interference tolerance, exceptional Rx sensitivity, low power consumption, and the ability to cover long distances, making it suitable for point-to-point connections across various low-frequency ISM bands.
The Raspberry Industrial PLC is an ideal choice for scenarios requiring long-range communication and IoT networks that involve sensors not connected to the electrical grid due to their location or primary use. Its application is widespread in Smart Cities, agricultural areas, and sensor/actuator networks that benefit from its key features. The technology is increasingly being adopted for smart grid management, fleet logistics, environmental monitoring, industrial IoT, and smart city applications due to its affordability and ease of use.
This PLC runs on a Linux-based operating system or Raspberry Pi OS, offering the flexibility and power of the Linux operating system. It includes various communication ports such as dual Ethernet, dual RS-485, WiFi, and Bluetooth, providing great flexibility and control for a wide array of industrial tasks.

- 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, tyres, 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, odour-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.
- Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
- Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.

* United-Kingdom consumers retain their statutory Right of Cancellation on these items. Its exercise is subject to the conditions and exclusions set out in the Statutory Right of Cancellation, and any reimbursement may be reduced to reflect a loss in value resulting from handling beyond inspection.
How to Request a Return Authorisation (RA)
While the same return policy applies, these orders require a separate contact process for returns.
- RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
- Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
