Large 8×8 LED Matrix Display




Have you worked with ready-made 8×8 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.

Large 8×8 LED Matrix Display




For this project, we will be building a single color large LED matrix display which is made up of a few large 8×8 LED matrix modules daisy-chained together. Each of these 8×8 LED matrix modules is around 144mm x 144mm in size.

The unique thing about this display is that other than the LEDs, one is able to view the background behind the display. This offers some creative use of these displays such as placing them against glass panels whereby people around it is able to see happenings behind the display. You may place some form of backing for your display if you find it distracting to read what is being displayed.

For this project, we will be using 10mm orange color LEDs to build the display. You may use LED sizes of your choice for your display. Commonly available sizes are 3mm, 5mm, 8mm, and 10mm.

Though our display is not designed to work with any particular microcontroller, we will be using the popular Arduino board in this instructables to drive it via SPI using only 3 signal wires. For those who prefer not to mess with too much wiring, the large 8×8 LED matrix module is available as a DIY kit at our Tindie Store.
