16x24 LED Matrix

Easy to use, chainable displays

These LED panels take care of all the work of making a big matrix display. Each panel has six 8x8 red matrix modules, for a 16x24 matrix. The panel has a HT1632C chip on the back with does all the multiplexing work for you and has a 3-pin SPI-like serial interface to talk to it and set LEDs on or off. There's a few extras as well, such as being able to change the brightness of the entire display, or blink the entire display at 1 Hz.

32x16 and 32x32 RGB LED Matrix

512 pixels of eye-blasting glory

Bring a little bit of Times Square into your home with our 16 x 32 and 32 x 32 RGB LED matrix panels. These panels are normally used to make video walls – here in New York we see them on the sides of buses and on bus stops – to display animations or short video clips. We thought they looked really cool so we picked up a few boxes from the factory. One has 512 bright RGB LEDs arranged in a 16x32 grid on the front, the other has 1024 LEDs in a 32x32 grid. Learn how to get this LED matrix up and running with an Arduino.

Animating Multiple LED Backpacks

Lights! Action! MORE LIGHTS! MORE ACTION!

Adafruit LED backpacks make it incredibly simple to add small bitmapped displays to a project. Each requires just four wires: power, ground and two communication lines to a microcontroller. Here’s how to use more than one 8x8 matrix backpack in an Arduino sketch.

Adafruit LED Backpacks

Control small LED matrices with ease

What's better than a single LED? Lots of LEDs! The matrices use a driver chip that does all the heavy lifting for you: They have a built in clock so they multiplex the display. They use constant-current drivers for ultra-bright, consistent color, 1/16 step display dimming, all via a simple I2C interface. Here is a detailed guide showing you how to solder, wire and control the display.

FPGA RGB Matrix

Control large RGB LED matrices using an FPGA

Adafruit currently sells a really cool 16x32 RGB LED matrix panel in their store that is "designed to be driven by an FPGA or other high speed processor." The purpose of this tutorial is to help you get started driving a small handful of these displays with the DE0-Nano board, which contains a mid-range Altera FPGA.
