3. Assembly Instructions

This kit requires self-assembly and soldering. Follow these steps carefully to construct your LED cube.

3.1 Understanding the PCB and LED Pins

Each PCB board is designed to hold 25 LEDs, forming one layer of the cube. The LEDs are 5mm RGB type with four pins. It is crucial to correctly identify the pin functions before soldering.

3.2 Soldering LEDs to PCB Layers

1. Carefully insert each LED into its designated slot on the PCB board, ensuring the correct pin orientation as indicated by the markings on the board and the LED diagram.
2. Solder all four pins of each LED to the PCB. Ensure strong, clean solder joints to prevent connectivity issues.
3. Repeat this process for all 25 LEDs on each of the five PCB layers.

3.3 Assembling the Cube Layers

Once all LEDs are soldered to their respective PCB layers, you will stack these layers to form the 5x5x5 cube structure. Use the provided copper columns to connect the layers.

1. Align the first PCB layer (bottom layer) with four copper columns. Securely fasten the columns to the designated holes on the PCB.
2. Place the second PCB layer on top of the copper columns, ensuring proper alignment. Solder or secure the layer to the columns.
3. Repeat this process for the remaining layers until all five layers are stacked and secured, forming the cube.

5. Maintenance

To ensure the longevity and optimal performance of your Treedix LED Cube Light DIY Kit, follow these maintenance guidelines:

• Cleaning: Gently wipe the cube with a soft, dry cloth to remove dust. Avoid using liquid cleaners directly on the LEDs or PCB.
• Handling: Handle the assembled cube with care to prevent damage to the soldered connections or LEDs.
• Storage: Store the cube in a dry, cool environment away from direct sunlight and extreme temperatures.
• Inspecting Connections: Periodically check soldered joints for any signs of corrosion or loosening, especially if the cube is frequently moved.

6. Troubleshooting

If you encounter issues with your LED cube, refer to the following common problems and solutions:

• LEDs not lighting up:
  • Check power connections (VCC, GND) to ensure they are correctly wired and receiving power.
  • Verify all solder joints for the affected LEDs and PCB connections. Cold or incomplete solder joints can prevent LEDs from functioning.
  • Ensure the data line (DIN/DOUT) is correctly connected to your microcontroller and that the programming code is running as expected.
• Incorrect colors or flickering:
  • This often indicates a data signal issue. Check the DIN/DOUT connections between layers and to the microcontroller.
  • Review your programming code for logic errors or incorrect LED addressing.
  • Ensure your power supply is adequate for the number of LEDs. Insufficient power can lead to flickering or incorrect colors, especially at higher brightness levels.
• Cube not recognized by microcontroller:
  • Confirm that the data pin specified in your code matches the physical pin connected on your microcontroller.
  • Check for continuity in the data line wiring.
  • Ensure the correct library (e.g., FastLED) is installed and properly configured in your development environment.
