1.1>.Soldering iron (<50 Watt) 1.2>.Rosin core (“radio”) solder 1.3>.Wire cutters 1.4>.Wire strippers 1.5>.Screwdriver 2>.Please be patient until the installation is complete. 3>The soldering iron can’t touch the components for a long time(1.0 second), otherwise it will damage the components. 4>.Pay attention to the positive and negative of the components. 5>.Strictly prohibit short circuit. 6>.User must install the LED according to the specified rules.Otherwise some LED will not light. 7>.Install complex components preferentially. 8>.Make sure all components are in right direction and right place. 9>.Please wear anti-static gloves or anti-static wristbands when installing electronic components.

10.Installation Steps(Please be patient): 1>.Step 1: Install 1pcs SMD components SOP-16 LM4863 Power Amplifier at U1. Verify
and confirm the installation direction of LM4863. The rectangular silk screen on the PCB coincides with the crystal oscillator on the LM4863 to locate the installation direction.
2>.Step 2: Randomly choose a pad on the PCB, and then melt the solder on this pad. 3>.Step 3: Fix LM4863: Use a soldering iron to melt tin on the pad just now and hold LM4863 with tweezers in the other hand to place/press on U1 to prevent movement. Take care to match and align each pads. Then remove soldering iron. Then remove tweezers after solder tin cooling and solidification. 4>.Step 4: Connect others pads on LM4863 to pads on PCB by tin and soldering iron. 5>.Step 5: Install 3pcs 10Kohm Metal Film Resistor at R2,R3,R4. 6>.Step 6: Install 1pcs 39Kohm Metal Film Resistor at R1. 7>.Step 7: Install 2pcs 1Kohm Metal Film Resistor at R6,R7. 8>.Step 8 Install 1pcs 100ohm Metal Film Resistor at R5. 9>.Step 9: Install 1pcs DO-41 1N4007 Diode at D1. Pay attention to the installation direction. There is a white mark on 1N4007 and a white mark on PCB which are used to confirm the installation direction. 10>.Step 10: Install 2pcs 0.1uF 104 Monolithic Capacitor at C3,C4. 11>.Step 11: Install 1pcs 3.5mm AUX Audio Socket at J5. 12>.Step 12: Install 1pcs ZIP-9 KA2284 LED Driver at U2. Pay attention to the installation direction. 13>.Step 13: Install 5pcs 5mm RGB LED at D2,D3,D4,D5,D6. Note:The longer pin is positive pole and connect to ` + ‘ pads. 14>.Step 14: Install 1pcs 16Pin DuPont Female Socket at FM. 15>.Step 15: Install 2pcs 4.7uF Electrolytic Capacitor at C2,C7.Pay attention to distinguish between positive and negative.The Longer pin is positive pole. 16>.Step 16: Install 1pcs 1uF Electrolytic Capacitor at C1.Pay attention to distinguish between positive and negative.The Longer pin is positive pole. 17>.Step 17: Install 2pcs 470uF Electrolytic Capacitor at C5,C6.Pay attention to distinguish between positive and negative.The Longer pin is positive pole. 18>.Step 18: Install 1pcs 8*8mm Self-locking Button at S6.
