Setup and Assembly
The PCB main board is pre-soldered and tested. Your primary task will be soldering the individual LED lamps to form the 3D cube structure. This process requires a basic electronic technology foundation and soldering ability. The main board features 256 holes designed to facilitate LED placement and soldering.
Assembly Steps:
- Prepare the LEDs: Carefully bend the leads of each LED as required for insertion into the PCB.
- Insert LEDs: Place the LEDs into the designated holes on the PCB main board.
- Solder Connections: Solder the LED leads to the PCB, ensuring secure and clean connections.
- Construct Layers: Assemble the LED layers, typically 16x16 grids, and then connect these layers vertically to form the 3D cube.
- Integrate Cube with Main Board: Securely attach the completed LED cube structure to the main PCB board.
- Power Connection: Connect the 5V power adapter to the main board.

Maintenance
To ensure the longevity and optimal performance of your 3D Led Cube, follow these general maintenance guidelines:
- Keep the cube in a dry environment to prevent moisture damage to electronic components.
- Avoid exposing the cube to extreme temperatures or direct sunlight for prolonged periods.
- Gently clean the LED surfaces and the main board with a soft, dry cloth to remove dust. Do not use liquid cleaners.
- Handle the assembled cube with care to prevent bending or damaging the LED leads.
Troubleshooting
If you encounter issues with your 3D Led Cube, consider the following common troubleshooting steps:
- LEDs not lighting up:
- Check all soldered connections for cold joints or bridges. A single stray solder drop can affect the board.
- Ensure the power adapter is correctly connected and providing 5V.
- Verify that individual LEDs are inserted with correct polarity.
- Inconsistent lighting patterns or flickering:
- This could indicate a loose connection or a faulty LED. Inspect the affected area carefully.
- Ensure the power supply is stable and sufficient.
- Missing components:
- If any components were missing upon arrival, contact customer support immediately for assistance.
- Software connection issues:
- Ensure the correct drivers are installed for the USB connection.
- Verify the software is compatible with your operating system.
- Check the download pin header connection.
For complex issues or if troubleshooting steps do not resolve the problem, please refer to the "Warranty and Support" section for contact information.
