The current 33k Ohm resistor allows you run from USB power. Will do, I have 3 free samples on the way from Vienna Austria that should arrive in two days. It is indeed compatible with the Max7xx libraries available. This kit can also be a great way to practice through-hole soldering. A code example for scrolling text will be available on the website.

Make sure you use a LED Matrix you use is common cathode.

Yeah I’ve used these before – http: This is where MobileWill has documented our adventures in electronics over les years. All you need to do is solder the header pins and soldder your own LED Matrix to the board.

It is indeed compatible with the Max7xx libraries available. All design files will be posted on http: I guess it should be. Interesting thing is that there are also more advanced part: Also the more modules affect performance. Hi, the AS from austriamicrosystems is 1: As you say, these chips are obviously a direct replacement for the Max72xx chips but with the advantage that they are: All this and there is a ready-made Arduino library for this IC.

If you need the LED Matrix you can buy the complete kit here: AS unfortunately you have to invert the input vs. I was actually able to do all 8 but as11107 reduced the brightness a tad.

Give it a try and let us know how you get on. Retired This product is no longer available lec sale. The current 33k Ohm resistor allows you run from USB power.

We hope to share our developments on the workbench and provide cool tools and gadgets with other makers. We’ll see in a week or so when I get the parts. Will do, I have 3 free samples on the way from Vienna Austria that should arrive in two days.

This product is no longer available for sale. I was just about to post my results. OK I have just wired up the example schematics and tried out the example code from the Max72xx library using the Austria Microsystems AS chip and indeed it works perfectly without any modification at all. I as11007 10 from Newark.

I too have a bunch of 8×8 matrixes lying around that I’m itching to get working It comes with all the SMD parts pre-soldered.
