I plan to design a 64x32 RGB LED Matrix and need some guidance from experts here... Project has to be extremely light-weight. Circuitry should be small size (excluding the Matrix) What Multiplexers, shift registers OR PWM I should be using. Should be cost effective but do not not want to compromis…

Description: Building a 192x32 matrix is no easy task, consider other options first, eg: [2 Panel Demo 1] (just some WS2811 LED strips fixed to a board, can be built in half a day)

Forgot to mention that each of RGB LED needs around 20mA.

Hi amudliar and welcome. Your requirements will not be easy, especially for a beginner! What level of colour control do you need? Have you looked for comercially available panels? How about 2 of these? 32x32 RGB LED Matrix Panel - 4mm Pitch : ID 607 : $29.95 : Adafruit Industries, Unique & fun D…

64x32 RGB is really 64x96, or 192x32, depending on how you arrange it, with either 3 anodes or 3 cathodes at every position. I think I would go with 192X32, with common cathode RGB LEDs. Use 192 anode drivers coming from 24 parts like cd74ac164, and some decent N-channel MOSFETs controlled by 4 sh…

What difference it will make if I do Common Anode? In your above approach you are recommending how many MOSFETS? 32 I believe using 4 shift registers (Cathode connected) In the image attached (thank you!) I see you connected 6 pins to 2 LEDs (3 pins of each RGB LED) and since I need 64 LEDs. Does …

You could try designing it is segments, using 8 Atmegas to drive 4 8x8 led matrices each, and linking them together with SPI. Probably not the cheapest option, but easily scale-able up to any size, up to 127 modules (but that would take tons of power)
