| Skip if | You need a plug-and-play commercial smart sprinkler, have no access to a 3D printer, or don’t want to handle PCB assembly and component sourcing. |
| Price | $15 |
| Format | Gerber files, BOM, pre-compiled firmware (.bin), and 3D-printed STL case files |
| One-line take | A rare $15 package that hands you the full hardware stack—board, code, and enclosure—for a four-valve smart sprinkler system. |
What you’re actually buying
Most DIY irrigation projects stall at the “now I need a board” stage. You sketch a circuit, hunt for a microcontroller, write firmware that fights with your valve drivers, and then realize you have no enclosure to keep the rain off your solder joints. Smart Sprinkler (Programador de Riego Inteligente) from Veltronic skips all that friction. For $15, you get a complete hardware blueprint: the Gerber files to send straight to PCBWAY or JLCPCB, a full bill of materials so you know exactly which components to order, and pre-compiled firmware that already knows how to talk to your hardware.
The scope here is what makes it interesting. You’re not getting a single-channel timer. This controller handles four independent solenoid valves plus a motor pump for pressure control, which means you can zone your garden or farm plot and manage water flow intelligently. The “Full” version of the system even integrates an environmental sensor for atmospheric pressure, temperature, and humidity—data you can use to automate watering based on actual weather conditions rather than a rigid schedule. (Smart Sprinkler)
The physical build is just as thoughtfully packaged. You receive STL files for the enclosure, ready for 3D printing. That means you can print a weather-resistant case that matches your board layout, giving your project a finished, professional look without needing CAD skills. Whether you’re building a smart garden controller for your backyard or a small-scale agricultural setup, the Smart Sprinkler file set gives you the entire stack in one purchase.
Why it’s on our radar
This is a rare find in the maker space: a fully specified, multi-zone irrigation controller available as a one-time $15 purchase. Most smart home or agricultural hardware projects require you to cobble together separate resources—a PCB design from one forum, firmware from another, and a case you have to model yourself. Veltronic has bundled the entire workflow into a single, coherent package. (Smart Sprinkler)
The inclusion of the motor pump control alongside the four valves is a specific detail that sets this apart from basic Arduino timer projects. It suggests a system designed for real-world pressure management, not just on/off valve switching. If you’re looking to build a smart sprinkler that can actually adapt to your water source and pressure needs, this is a strong starting point.
What actually matters
Before you buy, confirm a few things to make sure this fits your workshop: (Smart Sprinkler)
- 3D Printer Access: The enclosure is provided as STL files. You’ll need access to a 3D printer (your own or a local service) to get the physical case. If you’re not in the 3D printing ecosystem, this is a hard requirement. (Smart Sprinkler)
- PCB Fabrication Comfort: The Gerbers are ready for JLCPCB or PCBWAY, but you’ll still need to handle the assembly. If you’re comfortable with through-hole or SMD soldering and following a BOM, this is straightforward. If you’re brand new to electronics, pair this with a soldering tutorial or a friend who can help. (Smart Sprinkler)
- Firmware Transparency: The firmware is provided as a pre-compiled
.binfile. This is great for quick deployment, but if you want to modify the logic (e.g., add a new sensor or change the scheduling algorithm), you’ll need to understand the underlying codebase. Check the listing for source code availability if customization is a priority. (Smart Sprinkler) - Sensor Version: The listing mentions a “Full” version with an environmental sensor. Verify which version you’re getting at checkout to ensure you’re receiving the hardware design that matches your needs (basic 4-valve vs. full sensor suite). (Smart Sprinkler)

FAQ
Do I need to write the firmware myself?
No. The package includes a pre-compiled .bin firmware file. You can flash it directly to your microcontroller and start controlling your valves immediately. If you want to modify the behavior, you may need to look into the source code, but for standard operation, the provided firmware is ready to go. (Smart Sprinkler)
Can I use this with standard 24V solenoid valves? The listing specifies it controls four independent solenoid valves and a motor pump. You should verify the voltage and current requirements of your specific valves against the Bill of Materials (BOM) provided in the download to ensure compatibility. The BOM will list the exact driver components used, which will tell you what electrical specs the board is designed for. (Smart Sprinkler)
Is the 3D case just a box, or does it have features? The STL files are for the enclosure of the Smart Sprinkler controller. While the listing doesn’t detail every feature, a dedicated STL for a PCB-based project typically includes cutouts for buttons, LEDs, and connectors. Check the preview images in the Smart Sprinkler listing to see the case design before you print.
Bottom line
If you’re tired of half-finished DIY projects where the board design is the bottleneck, Smart Sprinkler (Programador de Riego Inteligente) is a clean, complete solution. At $15, you’re getting a full hardware stack—PCB, BOM, firmware, and 3D case—for a four-zone smart irrigation controller with pump control. It’s a serious project, but it’s a finished project in terms of design. If you have the tools to fabricate and assemble, this is one of the most cost-effective ways to build a smart sprinkler system from scratch.
