6.Installation Steps (Please be patient while starting the installation:)
Step 1: Install PCB-A. Install 4pcs 100ohm Metal Film Resistor on R2,R4,R6,R7.
Step 2: Install 3pcs 4.7K Metal Film Resistor on R1,R3,R5.
Step 3: Install 18pcs 3mm RGB LED at D1-D18.Pay attention to distinguish the positive and negative poles of LED and the Longer pin are positive pole. Control distance between PCB edge and LED head.
Step 4: Install 3pcs 47uF 16V Electrolytic Capacitor at C1,C2,C3.Pay attention to distinguish the positive and negative poles and the Longer pin are positive pole.A 2~3mm spacing is reserved between the capacitor and the PCB to facilitate bending of the capacitor for subsequent installation.
Step 5: Install 3pcs TO-92 S9014 Transistor at Q1,Q2,Q3.It is better to bend S9014's pin so that 2pcs PCB-A and PCB-B can better splicing.OK, PCB-A has been installed completed.
Step 6: Install PCB-B. Install 3pcs 100ohm Metal Film Resistor on R2,R4,R6.
Step 7: Install 3pcs 4.7K Metal Film Resistor on R1,R3,R5.
Step 8: Install 18pcs 3mm RGB LED at D1-D18.Pay attention to distinguish the positive and negative poles of LED and the Longer pin are positive pole. Control distance between PCB edge and LED head.
Step 9: Install 3pcs 47uF 16V Electrolytic Capacitor at C1,C2,C3.Pay attention to distinguish the positive and negative poles and the Longer pin are positive pole.A 2~3mm spacing is reserved between the capacitor and the PCB to facilitate bending of the capacitor for subsequent installation.
Step 10: Install 3pcs TO-92 S9014 Transistor at Q1,Q2,Q3. It is better to bend S9014's pin so that 2pcs PCB-A and PCB-B can better splicing.OK, PCB-B has been installed completed.
Step 11: Test.Connect 4.5V-5V to PCB-A and PCB-B separately.Preliminary welding success if LED are blinking automatically.
Step 12: Align the two positioning heads on PCB-A and PCB-B and then fixed with tin.
Step 13: Install Mini USB Socket at P1.
Step 14: Install 1pcs power switch at S.
Step 15: Fixed PCB-A and PCB-B on PCB-C.Align the two positioning heads and then fixed with tin.
Step 16: Install the top LED.Note the positive and negative of LED.At this point, the installation is complete!!
Step 17: Mounting Copper column and nut as bracket.
Step 18: Turn on the power and enjoy the effect.
