What is the Adafruit 4mm Pitch LED Matrix Portal S3?
LED matrices can be challenging to mount and display attractively. The bare boards have exposed electronics, making them less than ideal for living spaces. The Adafruit 4mm Pitch LED Matrix Portal S3 offers a powerful combination, but it still requires a suitable housing.
The Adafruit 4mm pitch LED matrix is a display panel with 62 columns and 32 rows of LEDs. The 4mm spacing between LEDs provides a good resolution for text, animations, and simple graphics, perfect for displaying weather data, stock tickers, or light patterns.
The Matrix Portal S3, featuring an Espressif ESP32-S3 chip, is a microcontroller board that connects directly to the LED matrix. Its built-in Wi-Fi and Bluetooth allow for wireless control via phone, computer, or the internet, enabling content updates without physical interaction.
Together, the LED panel and Portal S3 create an impressive digital sign. However, the exposed Portal S3 on the back of the matrix leaves the assembly looking like a bare circuit board. While functional on a desk or in a project box, a proper enclosure is needed for wall mounting or aesthetic display.
Community member SunsetRider designed a 3D printed enclosure specifically for this setup, sharing it freely on MakerWorld. This design was featured on Adafruit’s blog as part of their #3DThursday series, showcasing how to transform a bare board into a polished product.
The Design Challenge: Mounting an LED Matrix
Mounting an LED matrix involves several considerations. The large, flat panel needs secure support. The Portal S3 board connects to the back via header pins, requiring adequate space. Access to the Portal S3’s USB port for power and programming is essential. Finally, the entire assembly should be mountable on a wall or stable on a desk.
Makers often use standoffs, acrylic sheets, or custom laser-cut parts for mounting. These can be costly or require specialized tools. 3D printing offers a solution by allowing custom-fit enclosures with precise holes for screws and ports, printable at a low cost.
SunsetRider’s design provides a hangable enclosure, suitable for wall mounting with screws or adhesive strips. It securely holds the Portal S3 board to the back of the LED matrix, keeping the front display unobstructed and the back electronics neatly covered.
A key feature is the screw management. The design uses M2.5×4 screws for mounting the Portal S3 board and M3x8 screws for attaching the enclosure to the LED panel. This ensures a secure fit without damaging the boards.
This attention to detail simplifies assembly, avoiding the frustration of ill-fitting screws often encountered when mounting electronics.
Enclosure Features and Screw Specifications
This enclosure is specifically designed for the Adafruit 62×32 4mm-pitch LED matrix and the Matrix Portal S3 controller. Modifications would be needed for different matrix sizes.
Key specifications include:
- Compatible LED panel: Adafruit 62×32 4mm pitch LED matrix
- Compatible controller: Adafruit Matrix Portal S3
- Screws for Portal S3: M2.5×4 (four screws)
- Screws for LED panel: M3x8 (four screws)
- Mounting style: Hangable (wall-mountable)
- Print bed size: Designed for the full Bambu Lab P1/X1 print bed
- File location: MakerWorld, designer SunsetRider
The enclosure is a single-piece print requiring only the specified screws for assembly, eliminating the need for glue or tape.
The USB port on the Portal S3 remains accessible for power and programming without disassembling the unit.
Its hangable design allows for versatile placement, suitable for displaying clocks, weather forecasts, machine status, or event information, giving the LED matrix a professional appearance.
Compared to laser-cut acrylic frames or metal standoffs, this 3D printed enclosure is more cost-effective, easier to produce, and customizable in color. It offers a cleaner, simpler solution.
Limitations include its specific fit for the 62×32 panel and its large size, which requires a printer with a build volume of at least 256x256mm. Smaller printers may need to split the model or scale it down, potentially affecting screw hole alignment.
Printing Tips: Full Bed Utilization on P1/X1
The enclosure is designed to utilize the full 256x256mm build volume of Bambu Lab P1 and X1 printers. Printing as a single piece ensures greater strength, a cleaner look, and reduced post-processing time.
For P1 or X1 printers, consider these tips:
- Build plate adhesive: Use a clean PEI sheet with glue stick or hairspray for optimal adhesion and to prevent warping.
- Filament: PLA is sufficient; PETG offers better heat resistance and toughness.
- Brim: Add a brim in your slicer if you notice corners lifting.
- First layer: Ensure a level bed and correct nozzle height for a critical first layer.
- Infill: 15-20% infill provides a good balance of strength and print speed.
- Orientation: Print with the back side down for a smooth mounting surface.
Printers with larger build volumes (e.g., Creality K1 Max, Voron 2.4) can also print the enclosure in one piece. For smaller printers, splitting the model in the slicer and joining the parts with adhesive is an option. Scaling down the model is possible but requires careful checking of screw hole dimensions.
Where to Download the Files
The enclosure files are available for free on MakerWorld, under the designer SunsetRider. A search for the designer’s name on the platform should easily locate the model.
MakerWorld supports STL and 3MF files and allows users to share print settings, comments, and ratings. Leaving feedback on the design is encouraged to support the creator.
While MakerWorld is the primary source, the designer may also share files on other platforms like Printables or Thingiverse.
Import the downloaded files into your preferred slicer (Bambu Studio, Orca Slicer, PrusaSlicer, Cura). After setting your print parameters, slice and print. Expect several hours for printing time.
Gather the required M2.5×4 and M3x8 screws. Assemble the Portal S3 to the enclosure using the smaller screws, then attach the LED matrix with the larger screws. Connect the USB cable, upload your code, and the display is ready.
Why This Matters for Makers
This enclosure exemplifies the growing trend of 3D printable electronics housings within the maker community. Sharing custom designs online makes it easier for everyone to create polished, finished projects without extensive resources.
Traditional methods for creating enclosures, such as using off-the-shelf project boxes, manual cutting of materials like acrylic, or woodworking, often involve compromises in size, precision, or required skills. 3D printing allows for perfectly tailored designs that fit specific components precisely.
The Adafruit community actively participates in this trend, with projects like this highlighted weekly. This movement democratizes the creation of professional-looking electronic projects, making them more accessible and achievable for a wider audience.
