This is already my fourth review of LED panels for building displays. This review wasn’t originally part of my plans, and neither was buying these panels. In my previous review, I wrote that a seller’s mistake had left me with a controller, so I ordered another batch of LED panels for it. Since I had a specific display size in mind, I had to order panels with a resolution of 64×32 pixels. So, this is a brief review, a little theory, and answers to some of the questions I was asked after publishing the previous installments.

A while ago, a friend asked me to help him buy components for a scrolling text display, which he wanted to use to spruce up his little shop. We'd only ever seen them at other places, so we started figuring out how to put one together. We picked what we wanted, I placed the order, got everything, and decided to try it out at home first. There'll be an inspection, a teardown, and some tinkering with various bits of hardware—as usual :)
