Good afternoon,

I am building the LED matrix Gadget board.

Which way is "up" for the LED matrix?  I looked around, but could not find anything indicating how I should install them.  I would hate to have to unsolder them if I guessed wrong.

Thanks for the help!

V/R,

Tim

Hi Tim,

The pin-1 for the two led matrices is bottom left looking at the board right side up :).  Is that what you're asking?

Tim,

Also, here's the diagram:

And I've attached a photo of mine completed. I don't remember how pin 1 was marked, but maybe this'll help.

Hi Will,

Thanks for the quick reply.  I see the 'square' hole on the PCB, but I am not sure how to orient the LEDs (I have a 50-50 chance of getting it right!).

From your photo, it looks like if I install the LEDs with the sides the part numbers are printed on facing down relative to the board I should be OK.

Thanks again and have a nice weekend!

V/R,

Tim

Yes, the side with printing is facing down. I think I need to update the manual for this.

Thanks,
Liu
