I can provide you the product image and Details as needed if you can create?How could they? a schematic specifies each component type, value and so on, all that the PCB shows is where things interconnect but what is being connected? no way of knowing.
The 271 stamped is a resistor with the value of 270 ohm & the other one is Diode M7 and all the small black are resistor each with a value of 180 Ohm and all the white are SMD each with a value of 9 volt/ 1 Watt.It seems to be little more than a bunch of LEDs, each with a dedicated series resistor, all wired in parallel. There's something else near where the power wires come in, but not clear what they are (one has a 271 stamped on it).
OK well you have what you need, you can now draft out the circuit diagram, look:The 271 stamped is a resistor with the value of 270 ohm & the other one is Diode M7 and all the small black are resistor each with a value of 180 Ohm and all the white are SMD each with a value of 9 volt/ 1 Watt.
I hope I am able to clarify this.
Hi Thanks for your help.OK well you have what you need, you can now draft out the circuit diagram, look:
View attachment 294140
the larger pad is the -ve side of the LED.
View attachment 294142
I cut out an LED/resistor pad pair, you can see it above, it was copied from the left side of that to cut out, overlay this on the PCB:
View attachment 294144
now align it correctly:
View attachment 294145
That shows where the ends of the LED and resistor get soldered to the PCB surface. The outermost (black) copper area is the -ve side of the supply, so the LEDs are connected exactly as in that sample schematic I posted.
No, I cannot do that, you now have enough information to do it yourself, it is easy but time consuming, so get a move on!Hi Thanks for your help.
I am totally new in this and needed this circuit design for some urgent work today. I Will be very thankful to you if you can create this for me please.
