I purchased some of these dual color led-matrix located here

http://www.sparkfun.com/commerce/produc … cts_id=681

my problem is I can’t read the datasheet

which is pin 1 for starters and some of the other pins on the datasheet are too blurry to make out.has anybody figured out what pin is what and could share the info,I can’t be the only blind person out there can I ?:slight_smile:

the pinout is the same for both products:

  | COL   1       2       3       4       5       6       7       8

no prob on the specs, it is pretty tough to see

OK I’ve got a stupid follow up question…

how do you determine what is pin 1?

Thanks,

Alex

It’s the left side pin on the side with the part number stamped on it

thanks!

for future reference, does it show that anywhere in the data sheet? i couldn’t see it anywhere

no not really.But if you look at the way they show the pin one position and right under it they show the end with the part number so I tried that and it worked ok
