Red Pentagram LED Flash Lamp DIY Kit
Introduction:
Itis a simple mini Red Pentagram LED Flash Lamp DIY kit. The circuit is controlled by a DX158 LED driver chip, which can achieve automatic switching and cyclic playback of multifunctional light flashing modes after power ON. The flashing speed of the LED can also be adjusted by pressing the button.
Feature:
1>.Red LED Flashing
2> Automatic Switch Flashing Effect
3> Adjustable LED Flashing Speed
4> Micro USB 5V Power Supply
5>.DIY Manual Soldering
Parameter:
1>.Work Voltage:DC 5V
25 Power Type: Micro USB Socket
3>.LED Color: 80pcs Red
4>.Work Temperature:-40C~85C
5> Work Humidity:5%~95%RH
6> Size(Installed):78789mm
Use Methods:
1>.Input 5V work voltage from Micro USB Power Socket. Note:Users need to
prepare their own Micro USB power wire.
2>.Turn Toggle Switch to ON/OFF work power.
3>.Press Black Button to increase LED Flashing Speed. Note: the speed will
switch to the lowest speed if you continue to press the button, when reaching
the maximum speed.
4> Note: There is no memory function for speed, and every time the power is
restarted, the speed needs to be readjusted.
Component Listing:
1>.1pcs SOP-16 DX 158 LED Driver Controller
2>.1pcs Micro USB Power Socket

5>.Electronic competition
6>.Gift giving
7> .Crafts collection
8>.Home decoration
9>.Souvenir collection
10>.Graduation design
11> Holiday gifts
Installation Tips:
1>.User needs to prepare the welding tool at first.
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 package is DIY kit.It need finish install by user.
4>.The soldering iron can’t touch the components for a long time(1.0 second),
otherwise it will damage the components.
5>.Pay attention to the positive and negative of the components.
6>.Strictly prohibit short circuit.
7>.User must install the LED according to the specified rules.Otherwise some
LED will not light.
8>.Install complex components preferentially.
9>.Make sure all components are in right direction and right place.
10>.Itis strongly recommended to read the installation manual before starting
installation!!!
11> Please wear anti-static gloves or anti-static wristbands when installing
electronic components.
- Installation Steps(Please be patient install!!!):
Step 1: Install 1pcs SMD components SOP-16 0X158 at IC 1.Verify and confirm
the installation direction of DX158. There is a dot mark on one end of the IC
and there is a white dot mark on PCB silk screen 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 2: Randomly choose a pad on the PCB. and then melt the solder on this pad.
Step 3: Fix DX158: Use a soldering iron to melt tin on the pad just now and
hold OX 158 with tweezers in the other hand to place/press on IC1 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 DX158 to pads on PCB by tin and soldering iron.
Step 5: Install 1pcs 0.1uF 0805 Capacitor at C1.
Note : This component does not need to be installed. 
[Step 6: Install 1pes Micro USB Power Socket at DC1.
Step 7: Identify the positive(anode) and negative(cathode) lead of LEO. The
leads of the LED must be installed correctly, otherwise the LED cannot be
turned on.Here are four methods as following:
7.1>.According to the length of the LED lead to distinguish. The longer pin is
positive(anode) lead. The shorter pin is negative(cathode) lead.
7.2>.Identify the negative(cathode) of the LEO 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.
7.3>.1dentify by edge of plastic case. The negative(cathode) lead of the LED
should be the pin nearest the flat on the plastic case.
7.4>.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)
7.5>.Note:lf the flat on package disagrees with other indicators(short lead
large cathode lead end). then other indicators take priority. |.e. if the fiat
disagrees with the lead length,use the lead length as the cathode indicator.
Step 8: Install 80pcs 4mm Red LED at L1-L80.
Note: the shorter pin connect to flat edge pad as shown.
