Setup and Assembly Instructions
This kit requires soldering. The mainboard is pre-soldered and pre-programmed. Your primary task will be soldering the LEDs to form the 3D cube structure. Refer to the included paper instructions for detailed diagrams and steps.
Step 1: Prepare LEDs
Carefully bend the leads of the LEDs using the provided bending tool. Ensure consistent bending for proper alignment within the cube structure.

Step 2: Place and Solder LEDs
Insert the bent LEDs into the designated holes on the circuit board. Pay close attention to the polarity of each LED (anode and cathode) as indicated in the paper instructions. Solder each LED securely to the circuit board, ensuring good solder joints to prevent connectivity issues.
Step 3: Assemble LED Layers
Once individual LEDs are soldered, assemble them into layers as per the paper instructions. Connect these layers to form the complete 3D cube structure.
Step 4: Final Assembly
Mount the completed LED cube structure onto the mainboard. Ensure all electrical connections are secure and properly aligned.
Mainboard Functions Overview
The mainboard features several buttons for controlling the LED cube:
- USB-5V Power In: Connect the USB-DC cable here for power.
- Reset Button: Resets the cube to its initial state.
- Programming Connector: For advanced users to upload custom animations.
- Next Animation Button: Cycles through the built-in animation programs.
- Animation Loop Mode Button: Changes the animation loop behavior.
- Start/Pause Button: Starts or pauses the current animation.

Maintenance
The iCubeSmart LED Cube Kit requires minimal maintenance.
- Keep the cube clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid exposing the cube to moisture or extreme temperatures.
- Ensure all soldered connections remain secure. If an LED stops working, inspect its solder joints for any issues.
Troubleshooting
If you encounter any issues during assembly or operation, please refer to the following common problems and solutions:
- LEDs not lighting up:
- Check all solder joints for cold joints or bridges.
- Verify LED polarity during installation.
- Ensure the power supply is correctly connected and providing 5V.
- Animations not changing:
- Ensure the "Next Animation Button" is functioning correctly.
- Verify the mainboard program is intact (it comes pre-programmed).
- General issues:
