Introduction

Bring the Times Square atmosphere into your home with this stunning 64x32 square RGB LED matrix panel. These panels are commonly used to build video walls — in New York, you can spot them on the sides of buses and at bus stops displaying animations or short video clips. We thought they looked incredibly cool, so we sourced a few boxes straight from the factory.

This version is a 64x32 RGB LED matrix with 6mm pitch. Note that an Arduino UNO cannot drive a matrix of this size — it's simply too large! We recommend using an Arduino Mega, Raspberry Pi, BeagleBone Black (BBB), or any other device capable of handling RGB matrix displays with sufficient memory.

This matrix is similar to our 6mm pitch 32x32 RGB LED matrix panel, but twice as wide and looks great from a distance. If you need a 64x32 matrix for close-up viewing, check out our 3mm pitch, 4mm pitch, or 5mm pitch 64x32 RGB LED matrices.

The matrix features 2048 bright RGB LEDs on the front, arranged in a 64x32 grid. On the back are two IDC connectors (one input, one output — theoretically allowing daisy-chaining) and twelve 16-bit latches that enable driving the display at a 1:16 scan rate.

These displays are technically "chainable" — connecting one output to the next input — however our Arduino sample code does not currently support this feature.

These panels require 13 digital pins (6 data, 7 control) and a stable 5V power supply, with a maximum current draw of 4A per panel. We recommend using a regulated 5V/4A adapter with a 2.1mm jack. Check out our tutorial for more details!

Included:

• One 64x32 RGB panel
• One IDC cable
• One plug-in power cable

Keep in mind that these displays are designed to be driven by an FPGA or other high-speed processor — they have no built-in PWM control. Instead, you need to continuously redraw the screen to achieve PWM "manually." On an Arduino Mega running at 16 MHz, we managed 12-bit color (4096 colors) at 40% CPU utilization, but this display will perform even better when driven by an FPGA, CPLD, Propeller, XMOS, or any other high-speed multi-core controller. The good news is that the display comes pre-white-balanced with excellent uniformity, so when you turn on all LEDs, the white displayed won't show any noticeable color cast.

Of course, we won't just hand you a datasheet and say "good luck!" We provide complete wiring diagrams and ready-to-use Arduino library code with examples for drawing pixels, lines, rectangles, circles, and text. You'll have a color demo running within an hour! On Arduino, you'll need 16 digital pins and approximately 3200 bytes of RAM to buffer a 12-bit color image.

Please note:

• The back of the matrix may be green or black
• This product may come with one or two power connectors
• A short coupling data cable may be installed in the middle

Note: Shipping weight reflects UPS's new dimensional weight policy.
