Safety Information

Please read and understand all safety instructions before beginning assembly. This kit involves soldering, which requires caution.

Always work in a well-ventilated area when soldering.
Use appropriate personal protective equipment, such as safety glasses, to protect your eyes from solder splatter.
Ensure your soldering iron is on a heat-resistant stand and unplugged when not in use.
Avoid touching the hot tip of the soldering iron.
Keep all flammable materials away from the soldering area.
This product contains small parts and is recommended for ages 12 and up. Keep out of reach of small children.
Ensure correct polarity when connecting power sources (battery box or USB).

Identify Components: Use the provided component list and image to identify each part. Pay close attention to resistor values and capacitor polarities.
Prepare PCB: Lay out the main circuit board (CHR-T12 Controller) and the tree branch PCBs (CHR-T1 to CHR-T11).
Solder Resistors: Solder all resistors onto their designated spots on the main PCB and branch PCBs. Ensure correct values are placed in the correct locations as indicated by the PCB silk screen.
Solder Diodes and Capacitors: Solder the diodes (1N4007) and electrolytic capacitors (47uF 16V), paying careful attention to their polarity markings.
Solder Transistors: Solder the S9014 and S8050 transistors onto the main PCB.
Solder RGB LEDs: Solder the 37 RGB LEDs onto the branch PCBs. LEDs are polarized; ensure the longer leg (anode) matches the positive marking on the PCB.
Solder Other Components: Solder the self-locking switches, PX088A Music Chip (U1), and Passive Buzzer (LS1) onto the main PCB.
Assemble Tree Structure: Once all components are soldered onto the PCBs, begin assembling the 3D tree structure by connecting the branch PCBs to the central PCB spindle (CHR-T10A, CHR-T10B, CHR-T11A, CHR-T11B) and then to the main controller board. Use screws and nuts to secure connections where indicated.
Connect Power Components: Solder the DC Power Socket (J1) and connect the battery box (BAT) and USB power wire to the main PCB.
Final Check: Before applying power, carefully inspect all solder joints for shorts or cold joints. Ensure all components are correctly oriented.

Operating Instructions

Once assembly is complete and verified, you can power on your 3D RGB Christmas Tree.

Power Connection:
- Insert 3 AA batteries into the battery box, ensuring correct polarity.
- Alternatively, connect the provided USB power cable to a 5V USB power source (e.g., computer USB port, USB wall adapter) and plug the other end into the DC power socket on the tree's base.
Activation: Once power is supplied, the Christmas tree will automatically begin flashing its RGB LEDs and playing simple music.
Functionality: The kit is designed for automatic operation of light patterns and music. There are no user-adjustable settings for light modes or music playback.

Maintenance

The MiOYOOW 3D RGB Christmas Tree LED DIY Kit requires minimal maintenance.

Cleaning: Use a soft, dry cloth to gently wipe dust from the circuit boards and LEDs. Do not use liquids or abrasive cleaners.
Storage: When not in use, store the assembled tree in a dry, cool place away from direct sunlight and excessive humidity.
Battery Replacement: If using batteries, replace them when the lights dim or music becomes distorted. Remove batteries if storing for extended periods to prevent leakage.

Troubleshooting

If you encounter issues with your MiOYOOW 3D RGB Christmas Tree, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
Lights do not turn on / No music	No power or low battery. Incorrect component polarity (e.g., LEDs, diodes, capacitors). Cold solder joint or short circuit. Component inserted in wrong location.	Check battery installation or USB power connection. Verify polarity of all polarized components. Inspect all solder joints for proper connection and absence of bridges. Re-solder as needed. Double-check component placement against the PCB silk screen and component list.
Some LEDs not lighting up	Faulty LED. Incorrect LED polarity. Poor solder joint on specific LED.	Test individual LEDs if possible. Ensure LED polarity matches PCB markings. Re-solder the affected LED's connections.
Music is distorted or absent	Buzzer (LS1) or music chip (U1) incorrectly soldered. Faulty buzzer or chip.	Check solder joints for LS1 and U1. Ensure U1 is inserted correctly (if socketed).

If you continue to experience issues, please contact MiOYOOW customer support for further assistance.
