 That, right there, is my product pick of the week. It is the Quad Alpha Numeric 14 Segment LED Backpack. It runs over I squared C, so you know what we did. We did what we always do. We added a STEMA QT slash quick port. There's actually two of them back there. Light up individual segments if you want. Yee-haw, my friend. I have five of these displays, each color. I have them all plugged into each other on the back using the STEMA QT, and then I have that plugged into a little cutie pie here. Each of these, I have set the jumpers on to give them unique addresses. Alpha stuff, it says Alpha Numeric Display. Once you have this set up, you can just throw long lines of text added or strings of numbers. It knows what to do, so there's nothing you have to do to manage it. It just access a single display, which is terrific, the library is excellent. It is the Quad Alpha Numeric 14 Segment LED Backpack Display with STEMA QT.
