Chain RGB LED - Arduino

I would like to chain up 64x32 RGB matrix LED by using Arduino. Is there any way to make it?

Perhaps look at using a HypnoCube HypnoLSD serial driver between the Aduino and the LED matrix hypnocube | Hypnocube LED Serial Driver https://www.youtube.com/watch?v=SzpcPrnh9LY Single HypnoLSD serial…

Is it something you want to use for your hobby or something to be produced commercially?

64 x 32 x 3 colors equals to 6144 channels to be driven.
I wouldn't personally want to build that myself from port expanders like PCF8575.

How about using some ready-made module like this one? Have a look at the display datasheet there with a photo of that module from the rear, with all the ICs.
I think they already did some calculations to support this statement "Please note you cannot use an Arduino UNO to drive this size, its way too big! Use an Arduino Mega, Raspberry Pi, BBB or other device that can handle displaying to RGB matricies and has plenty of RAM."

Hi,
Probably you could try building your own using some WS2812B addressable led strips, some ready-made Displays are too available, there are a lot of tutorials out there,The WS2812B takes 3bytes per led, do the math before choosing your controller.

Cheers,
Sakthi

Single HypnoLSD serial driver can support up to 10,000 LEDs

Hi there.. This is something that I have to study under R&D.. I get the 64x32 LED panel for 12 units. Yes, it just like this one but to make it chain to each other and build up until 4x3 panel of 64x32 is hard to do. Now I am using arduino Mega ADK with the library given by gitHub. unfortunately, the library only support to display 1 panel of 64x32 RGB LED only..
Now I am stuck and have no idea how to make it. Still trying to adjust the library and produce the compatible one with chain panel application.

If you can drive one panel then can you multiplex them?

Use the same code to drive each in sequence, it's the way multiple 7 segment displays can be driven using 7 outputs + 1 for each individual digit to enable them.
