Hi all,

I need a quick double check.

I'm looking at using a small 8x8 LED matrix in a project. It's been
awhile since I've dealt with them. If I recall correctly, in an 8x8
LED matrix what makes it common cathode or common anode is really just
how it's wired, correct? Since I'm making my own board, I could get
either and have it work as long as I adjusted the wiring for the
correct pinout?

I haven't done a ton of sourcing yet, but a preliminary investigate
showed CA as a bit cheaper, though the driver I want to use prefers
CC.

Thank you!

Josh
