Re: Power for 6 displays

Hi If you're planning to make this semi-permanent and trapping your Eleven in the project the neatest path I think would be to solder your power wires direct to the 5V and GND pads on the underside. You might also be tempted to make up a micro-USB cable that only provides the 5V and GND wires. If it...

Re: Power for 6 displays

Hi,

Re: DMD2 4x4 display

Hi Ahmed

Because I've found it unstable with ATmega328 based Arduino above 6, I've kept my designs to 6 or fewer. Others on this forum have stated they've had success with more.

Re: Death of our forum?

Crickets in reply to this. What a shame.

I'm up for a working bee to fix it up too. I'm presuming the forum has tools tools for mods to delete members and all their posts?
