Here’s my dumb question - if I want to use this to drive a COM-00682 dual color 8x8 matrix, do I need 2 (one for each color), or just one? IIRC, there’s 24 pins on the matrix. I’m talking individual LED control, not text.
Ultimately, I need to figure out how to use 4 of those COM-00682s for 256 dual color LEDs, but fine getting started w/ one. Using an Arduino. Thanks.

I read the datasheet and comments, but still wonder if this is the right part for my application.
I want to hook this up to switch power to a dc subpanel in my car. So I want this to close when I turn on the ignition (I have a switched wire to tap into), and when it closes, it completes a circuit of heavy wires hooked up directly to the battery. I see discussion about 5v and 12v to activate this relay, so that’s really my question. Thanks!
