Installation Steps(Please be patient install!!!)

1. Step 1 : Install 1pcs SMD components RDA5807 FM Receiver at U2. Verify and confirm the installation direction of RDA5807. The rectangular silk screen on the PCB coincides with the crystal oscillator on the RDA5807 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 RDA5807: Use a soldering iron to melt tin on the pad just now and hold RDA5807 with tweezers in the other hand to place/press on U2 to prevent movement. Take care to match and align each pads. Then remove soldering iron. Then remove tweezers after solder tin coolina and solidification.
4. Step 4 : Connect others pads on RDA5807 to pads on PCB by tin and soldering iron.
5. Step 5 : Install 1pcs 100hm Metal Film Resistor at R6.
6. Step 6 : Install 2pcs 1000hm Metal Film Resistor at R19, R20.
7. Step 7 : Install 2pcs 6.8Kohm Metal Film Resistor at R12, R15.
8. Step 8 : Install 4pcs 1Kohm Metal Film Resistor at R9, R13, R16, R17.
9. Step 9 : Install 11pcs 10Kohm Metal Film Resistor at R1-R5,R7,8,11,R14, R15, R18.
10. Step 10 ; Install 3pcs DO-41 1N4007 Diode at D11,D12, D13. Pay attention to the installation direction. There is a black mark on 1N4007 and a white mark on PCB which are used to confirm the installation direction.
11. Step 11 : Install 1pcs 11.0592MHz Crystal Oscillator at Y1.
12. Step 12 : Install 1pcs DIP-8 IC Socket at U3. There is a gap mark on one end of the IC Socket and there is a gap mark on PCB silk screen where the IC Socket can place on. These two marks are corresponding to each other and are used to specify the installation direction of the IC Socket.
13. Step 13 : Install 1pcs DIP-40 IC Socket at U1. There is a gap mark on one end of the IC Socket and there is a gap mark on PCB silk screen where the IC Socket can place on. These two marks are corresponding to each other and are used to specify the installation direction of the IC Socket.
14. Step 14 : Install 2pcs 22pF Ceramic Capacitor at C1,C2.
15. Step 15 : Install 3pcs 0.1uF 104 Monolithic Capacitor at C10,C12, C13.
16. Step 16 : Confirm and identify the installation direction of the KA2284.
17. Step 17 : Install 2pcs ZIP-9 KA2284 LED Driver at KA2284.
18. Step 18 : Identify the positive(anode) and negative(cathode) lead of LED. The leads of the LED must be installed correctly, otherwise the LED cannot be turned on. Here are four methods as following
19. According to the length of the LED lead to distinguish. The longer pin is positive(anode) lead. The shorter pin is negative(cathode) lead.
20. Identify the negative(cathode) of the LED is to look into the plastic case where one can see that the negative(cathode) is much thicker/bigger inside the plastic case than the anode lead.
21. Identify by edge of plastic case. The negative(cathode) lead of the LED shoul be the pin nearest the flat on the plastic case.
22. Test by 3V battery or multimeter. The pin is positive(anode) lead which has connect to positive of 3V if LED can light up after connect 3V power supply. (LED can not be powered directly from 3V for a short time: less then 0.5second)
23. Note: If the flat on package disagrees with other indicators(short lead, large cathode lead end), then other indicators take priority. I.e. if the flat disagrees with the lead length,use the lead length as the cathode indicator.
24. Step 19: Install 10pcs 5mm RGB LED at LED1-LED10.
25. Step 20 : Install 1pcs 16Pin DuPont Female Socket at LCD1602.
