If you love to play around with dot matrix displays and enjoy the intricacies of multiplexing various rows and columns to create imagery, text or even creative facial gestures for robots, then you’re going to love this massive 32x32 RGB LED Matrix Panel. This awesome panel offers a full suite of 1024 RGB LED’s with 4mm Pitch, and can also be Cascaded with more panels to create extra-large dot matrix LED Displays for really impressive projects.

Compared to the MAX7219 chips that are utilised for the smaller, lower power 8x8 dot matrix displays that we’re all quite fond of, these larger RGB LED Displays use the higher power SH74HC based shift registers to deliver a good amount of power for a striking level of brightness. This, in addition to the 4mm pitch of the LED units, ensure that this display will be more than just easy to see, but actually difficult to ignore.

In terms of usability, this matrix display is relatively easy to operate with the connection diagram included in the images above, and features two IDC connectors on the back – one for DATA_IN and one for DATA_OUT. The DATA_IN port is where you would typically connect a microcontroller, while the DATA_OUT port is the one that’s used to cascade these panels. However, it’s important (and kind of unfortunate) to note that that some Arduino Boards will not be fast enough to handle multiple panels simultaneously, so if you are eager to cascade two (2) or more of these panels together to create extra-large matrix panels, you will need to utilise a faster MCU, or consider getting one of the larger single units such as the 32x64 RGB LED Matrix Panel instead.

Typical Applications for these 32x32 Cascadable RGB LED Matrix Panels:

While testing and experimenting with these awesome high density 32x32 RGB LED Matrix Panels, we found that the square shape of this panel lent itself well to some really interesting projects, and compared to the rectangular style panels, this square shape allowed us to enjoy some rather unique projects, such as:

  • Building a makeshift digital Battleships game, which would light up the corresponding LED’s depending on whether an enemy ship was there, allowing users to even play against a computer that used a random generator to decide on where to attack next.
  • Creating a retro style pixel-art display, which cycles through fun images from favourite games and shows in the past – or utilise random generation to create pixelated “Abstract” art that slowly changes over time.
  • Making a digital “Snow-Globe” that reacts to shakes, tilts and acceleration in various directions, to mix, blend or disrupt colourful patterns – and then adding a mechanism that shakes it about from time to time to keep it interesting.

While there are definitely loads of other exciting projects that you could enjoy with these fantastic panels (and even more so if you are planning on using multiple panels in cascade style), we really enjoyed these three during our testing and quality assurance, but if you have other great ideas, we’d love to hear all about them on social media once you’ve managed to build and demonstrate the awesomeness of your great ideas!
