The RGB 8x8 display reference design has a matrix of 64 full color LEDs. Each LED can be individually controlled by ARC to form messages, pictures, games, and more! A unique feature of this display is that it is a smaller form factor (48x48mm) than common RGB matrix displays (60x60mm). We want to share these files with you so you can create your own!
