5x7 led matrix datasheet

Hi Guyzz

Just got 16 of these

LM-0355MVWB 5x7 LED Matrix

I think they are from Rohm , but can not find any pinout/DS

They are on a used PCB , and seems to have 2 x 9 pins like a DIP.
Well seems like one pin is missing (pin 17).

Anyone have some suggestion ??

TIA

led matrix datasheet

This website www.datasheet4u.com has the datashet for LM-2035 by Rohm.
Maybe you see some similarities.

Also, using 5V and a resistor to limit the current (1kΩ is fine) you can find the pinout yourself. It should be pretty straightforward, probably easier than finding the datasheet.
With a low voltage like that and limited current you do not run any risk of damaging the LED's.
 


5x7 led matrix pinout

@BENOIT

Thank you for the link .....

I am afraid that it is not my pinout , as i have 18 pins on the Matrix , not just 12 pins.

Thanx
Anyway .....

5x7 matrix pinout

Did you try the 5V and resistor method?
That will give you the pinout in no time.
