So I need a scrolling red LED ticker to preferably buy premade in 4ft+ lenths and 6in to 1ft heights. Now most of the crap I'm finding comes with remote, or USB,etc.. I'm looking for something that just hooks up via UART or CAT5. I plan on having my own microcontroller powering them in singles or arrays. Any advice to links to circuits or where I could buy em. I found a couple really close ones on Allibaba but they said hooks up via USB, CAT5, and Remote. Didn't really wanna waist anyones time upstairs so I thought I'd ask you then move or post it there once its serious.
