1.2>.Rosin core ("radio") solder
1.3>.Wire cutters
1.4>.Wire strippers
1.5>.Philips screwdriver
2>.The soldering iron can't touch the components for a long time(1.0
second), otherwise it will damage the components.
3>.Pay attention to the positive and negative of the components.
4>.Strictly prohibit short circuit.
5>.User must install the LED according to the specified rules.Otherwise
some LED will not light.
6>.Install complex components preferentially.
7>.Make sure all components are in right direction and right place.
starting installation!!!
8>.Please wear anti-static gloves or anti-static wristbands when installing
electronic components.
9. Installation Steps(Please be patient):
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.
Step 2: Randomly choose a pad on the PCB, and then melt the solder on
this pad.
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 cooling and solidification.
Step 4: Connect others pads on RDA5807 to pads on PCB by tin and
soldering iron.
Step 5: Install 1pcs 10ohm Metal Film Resistor at R6.
Step 6: Install 2pcs 100ohm Metal Film Resistor at R19, R20.
Step 7: Install 2pcs 6.8Kohm Metal Film Resistor at R12, R15.
Step 8: Install 4pcs 1Kohm Metal Film Resistor at R9, R13 ,R16, R17.
Step 9: Install 11pcs 10Kohm Metal Film Resistor at R1-R5, R7, R8, R11,
R14, R15, R18.
Step 10: Install 1pcs 11.0592MHz Crystal Oscillator at Y1.
Step 11: 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.

Step 12: 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.
Step 13: Install 2pcs 22pF Ceramic Capacitor at C1, C2.
Step 14: Install 3pcs 0.1uF 104 Monolithic Capacitor at C10, C12, C13.
Step 15: Confirm and identify the installation direction of the KA2284.
Step 16: Install 2pcs ZIP-9 KA2284 LED Driver at KA2284.
Step 17: 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:
1. According to the length of the LED lead to distinguish. The longer
pin is positive(anode) lead. The shorter pin is negative(cathode) lead.
2. 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.
3. Identify by edge of plastic case. The negative(cathode) lead of the
LED should be the pin nearest the flat on the plastic case.
4.Test by 3V battery or multimeter. The pin is positive(anode) lead
which has connect to the positive of 3V if LED can light up after connect 3V
power supply.(LED should not be powered directly from the 3V for a short
time:less then 0.5second)
5.It is positive(anode) where the white mark “+” pointing to on PCB.
Step 18: Install 10pcs 5mm RGB LED at LED1-LED10.
Step 19: Install 1pcs 16Pin DuPont Female Socket at LCD1602.
Step 20: Bend the pins of only one 4.7uF electrolytic capacitor about 2mm.
Note:Just for only one!
Step 21: Install this Electrolytic Capacitor at C7.
Step 22: Install others 8pcs 4.7uF Electrolytic Capacitor at C3, C5, C6, C8,
C11, C14, C15, C16 .
Step 23: Install 2pcs 4.100uF Electrolytic Capacitor at C4,C9.
Note: Pay attention to distinguish between positive and negative.The
Longer pin is positive pole.
The capacitor needs to be placed horizontally, keep a distance of 2mm
between the capacitor and the PCB when installing.
Step 24: Install 1pcs DC-005 Power Socket at J1.
Step 25: Install 2pcs 5.8*5.8mm Self-locking Button at S4, S6.

Step 26: Install 4pcs 6*6*20mm Black Button atS1, S2, S3, S5.
Step 27: Install 1pcs DIP-8 IC LM386N at U3.
There is a gap mark on one end of the IC and there is a gap mark on DIP-8
IC Socket where the IC can place on.
These two marks are corresponding to each other and are used to specify
the installation direction of the IC.
Step 28: Install 1pcs DIP-40 IC STC89C52RC.
There is a gap mark on one end of the IC and there is a gap mark on
DIP-40 IC Socket where the IC can place on.
These two marks are corresponding to each other and are used to specify
the installation direction of the IC.
Step 29: Fix 4pcs M3*10mm Copper Pillar and 4pcs M3*8mm Screw on
PCB.
Step 30: Install 1pcs 16Pin Male Socket on the black of LCD1602 display
screen.
Step 31: Plug LCD1602 display screen on 16Pin DuPont Female Socket.
Note: Don't use screws to fix it for now.
Step 32: Install 1pcs 75ohm Antenna at ANT. Keep a distance more than
5mm from PCB and fix by tin(not screw). Note: the antenna should be installed
on the back of the PCB.
Step 33: Place 2pcs red button cap on Self-locking Button.
Step 34: Connect speaker to PCB at SP by 20cm red/black Cable. The
speaker does not distinguish between positive and negative.
Step 35: Tear off the protective film on the surface of the acrylic shell.
Step 36: Fix Top Acrylic Board and LCD1602 Acrylic Board on Copper
Pillar by 4pcs M3*6mm Screw.
Step 37: Fix 4pcs Side Acrylic Board by 6pcs M3*6mm Screw and 6pcs
M3 Nuts.
Step 38: Fix speaker on Acrylic Bottom Board by 4pcs M3*10mm Screws
and 4pcs M3 Nuts.
Step 39: Install Speaker Acrylic Board by 4pcs M3*6mm Screw and 4pcs
M3 Nuts.
Step 40: Connect to power supply and enjoy the effect.
