“Have you worked with ready-made 8x8 LED matrix as displays? They come in various sizes and are quite interesting to work with. A large readily available size is around 60mm x 60mm. However, if you are looking for a much larger ready-made LED matrix, you may be out of luck.
For this project, we will be building a single color large LED matrix display which is made up of a few large 8x8 LED 10mm matrix modules daisy-chained together. Each of these 8x8 LED matrix modules is around 100mm x 100mm in size.”
