Installation Notes
Users should follow the PCB silkscreen and component list for installation.

Installation Steps

1. Step 1: Install PCB-A. Install 4pcs 100ohm Metal Film Resistor on R2, R4, R6, R7.
2. Step 2: Install 3pcs 4.7K Metal Film Resistor on R1, R3, R5.
3. Step 3: Install 18pcs 3mm RGB LED at D1-D18. Pay attention to distinguishing the positive and negative poles of the LED, and the longer pin is the positive pole. Control the distance between the PCB edge and the LED head.
4. Step 4: Install 3pcs 47uF 16V Electrolytic Capacitor at C1, C2, C3. Pay attention to distinguishing the positive and negative poles and the longer pin is the positive pole. Reserve a 2~3mm spacing between the capacitor and the PCB for bending the capacitor during subsequent installation.
5. Step 5: Install 3pcs TO-92 S9014 Transistor at Q1, Q2, Q3. It is better to bend S9014’s pin so that 2 PCs PCB-A and PCB-B can be better spliced. PCB-A installation is now completed.

Follow the provided diagram for further installation steps.
