Maybe they were ‘inspired’ by it.

But it’s a better product as far as brightness is concerned. It’s got LED drivers and all. Of course if you want to improve soldering skills, mine is better. Self assembled ;-)

Looks like rainbowduino stole your design :)

Hi, have a look at my shop please ;-) I offer a full DIY kit including the LED matrix, and just the bare PCB. If you have access to a PCB manufacturing service that is cheaper for you, just download the gerber files and have the boards made locally. There is demo code as well. Everything is open source ;-)

Sort of. You can mount them next to each other, but there will be a gap of 2-3 mm between the modules. It might get better after milling/grinding off some unused space at the edges of the PCB. A dirty job.

I really never designed it with building a bigger display (scrolling text etc.) in mind, because it would have been quite costly with many modules in a row. But you can always get a Rainbowduino, which should work that way. And of course I can’t compete with a real business selling these things.

Or you could download my design files and fix it for your needs ;-)

Are these modular. Can you put them together for large displays?

Called? I could give you the German name for them, but that wouldn’t help I guess. For me they’re just ‘female headers’ when I use the English language ;-) There are the cheap ones (square pins) and the ‘precision’ / ‘machined’ types (round pins). The 10pin female headers used on the board are the cheap ones, the 8pin headers are the ‘better’ ones.

What are those female headers called? I’ve been trying to figure this out for a while.
