64x32 RGB LED Matrix - 4mm pitch

This 64 x 32 square RGB LED matrix panel can bring the vibrancy of Times Square to your home. Used normally for video walls, these panels can be seen displaying animations or short videos on the sides of busses and bus stops around New York City. Seeking an impressive display, we sourced a few of these panels from a factory.

This version features the 4mm pitch 64x32 RGB LED Matrix. Please bear in mind that an Arduino UNO is not suitable for driving this size matrix; an Arduino Mega, Raspberry Pi, BBB or similar device with sufficient RAM and the capacity to display to RGB matrices is required.

This product is a lot like our 64x32 RGB LED matrix panel with 3mm pitch, but with an increased 4mm pitch that enables you to admire it even from further away. It has been designed with a 160-degree wide-angle view for optimal indoor visibility even in low light conditions. For an even larger pitch, explore our 6mm and 5mm pitch 64x32 RGB LED Matrix panels.

This matrix has 2048 bright RGB LEDs arranged in a 64x32 grid on the front. On the back, there is a PCB with two IDC connectors (one input, one output: in theory you can chain these together) and 12 16-bit latches that allow you to drive the display with a 1:16 scan rate.

These displays are technically 'chainable' - connect one output to the next input - but our Arduino example code does not support this (yet). It requires a high-speed processor and more RAM than the Arduino has!

These panels require 13 digital pins (6-bit data, 7-bit control) and a good 5V supply, up to 4A per panel. We suggest our 4A regulated 5V adapter and then connecting a 2.1mm jack. Please check out our tutorial for more details!

Comes with:

• A single 64x32 RGB panel,
• An IDC cable
• A plug in power cable

RAM & Processor Requirements

Keep in mind that these displays were designed to be driven by FPGAs or other high speed processors: they do not have built in PWM control of any kind. Instead, you're supposed to redraw the screen over and over to 'manually' PWM the whole thing.

You'll need about 1600 bytes of RAM to buffer the 12-bit color image. You cannot use this size panel with an Arduino UNO (ATmega328) or ATmega32u4 - you need a chip with more RAM! These displays are technically 'chainable' - connect one output to the next input - as long as you have the RAM and CPU to handle it

This display does best with a high speed, high RAM microcontroller like a SAMD21, SAMD51, ESP32, etc. 8-bit micros are going to struggle if they work at all. The good news is that the display is pre-white balanced with nice uniformity so if you turn on all the LEDs it's not a particularly tinted white.

Power Requirements

There's a lot of LEDs! You may need up to 4A per panel. We suggest our 4A regulated 5V adapter and then connecting a 2.1mm jack. Please check out our tutorials for more details!

Connection Requirements

These displays require 13 GPIO pins to control. You may have to use consecutive or special pins depending on the driver firmware. We'll be honest: folks who try to wire directly are usually not successful, its easy to get confused and misconnect. For that reason we strongly recommend a ready-to-go board or adapter that makes wiring as easy as plugging in the cables and powering with 5V

• We recommend the Matrix Portal ESP32-S3 for a WiFi-enabled powerful plug-and-play board
• The original Matrix Portal with SAMD51 is also a great plug-and-play board if you happen to want a Cortex M4 as a main processor (we recommend the S3 version, above, as it is faster and has more memory)
• For many Arduino-shaped boards, you may be able to use our RGB Matrix Shield (check the product page and tutorial for which Arduino-like boards can be used)
• We also have RGB Matrix FeatherWings for many Feather boards (check the product page and tutorial for which Feather boards can be used)
• For Raspberry Pi computers, our RGB Matrix Bonnet is fully plug-and-play for powerful Linux-controlled displays.

We've also got our great Protomatter library that works in Arduino and CircuitPython for quick usage of many chained matrices.

Please note! These panels are remainder stock from factories that make huge light boards. For that reason, the look and size might vary from batch to batch, even though the basic operation, codebase and tutorial is the same.

Please also note: 

• The back of the matrix will either be green or black
• This product may come with one or two power connections
• There may be a short coupling data cable installed in the center
