I just realized I never uploaded any information on ordering these boards, so here it is:

You can find the board at https://oshpark.com/shared_projects/GrS5E55G.

You can also find the design files in the github repo.

That's all, folks!

P.S. I'd like to ask that you order a few dollars' worth at least from OSHPark: The shipping may be free to you, but it isn't to them!

Not much to say here, but the arduino library has been uploaded to the github repository.

I haven't yet changed the code to work with LEDs soldered differently from mine — I'll try to do that later today though.

Last Tuesday, 15 of these arrived.

Yeah, I'll need to redo the silkscreen—OSHPark understandably couldn't handle those tiny letters—but testing showed all the traces worked, even that one that's really close to the PCB edge.

So, I assembled two of them.

While assembling, I tested them with the multimeter—it turns out it's really hard to keep track of which LED is oriented in what direction.

Also, 0603s are generally quite annoying.

A quick test on a breadboard showed they worked great—so I went to the arduino and started coding.

After some initial tests with port manipulation, I started writing a library. It's done and working, and I'll upload the code when I add some more comments ;)

EDIT 1: the board files have been changed to improve the silkscreen & increase track width— see github. Yes, the gerbers have also been updated :)

I changed the design, getting rid of castellated holes and fixing a mistake I had in which one LED was going in the wrong direction.

Here's the old screenshots - I will be removing them from the gallery.
