![]() Individual 8×8 matrixes can be combined to make larger displays. Since I used the Common Row Cathode arrangement of the matrix, I will mainly discuss it here and you can extend the same logic to. There are common configurations for a LED matrix: a) Common Row Anode. DIP pixels are coarse and bright, and are best for large-scale outdoor displays such as scoreboard, billboards, or other displays where the audience is much further from the display. The most common type of LED matrix used with the Arduino is the 8×8 LED matrix. The tutorial I used to make the 8x8 LED matrix in this project can be found here. Dots in Place (DIP) pixels are often composed of three colored dots mounted in the middle of the pixel. Globally, SMD pixels make up the vast majority of indoor DVLED displays.

Surface Mount Diode (SMD) pixels are composed of modularly packaged color mounted directly on the PCB surface, hence the name. ![]() With IMD-style pixels, fine pitch displays are less vulnerable to physical impact, excessive heat, and other environmental issues. SMD becomes fragile at tight pixel-pitch, creating an increased risk of damage at tighter pitches. Integrated Matrix Device, or 4-in-1 Surface Mount Diode, (IMD) pixels are similar to the Surface Mount Diode (SMD see below) but have four times as many pixels per module. COB pixels are suitable for indoor displays where the audience will be closer to the screen, such as wayfinding displays, advertisements, or menu boards. Due to the layering techniques used on the surface of these pixels, COB pixels are very durable. Chip on Board (COB) pixels are constructed with the color chips mounted directly on the printed circuit board (PCB), allowing for tight pixel pitch, contrast, viewing angles and great color.
