Adafruit - RGB Dot-matrix LED panel - 32x32 pixel (128x128mm)

RGB dot-martrix LED modul. 32x32 RGB-pixel med 4mm afstand. Panelstørrelse på 128x128mm. Inkl. kabler for tilslutning/sammenkobling af moduler.

Bring a little bit of Times Square into your home with this totally adorable square 32 x 32 RGB LED matrix panel. These panels are normally used to make video walls, you see them on the sides of busses and bus stops, to display animations or short video clips. They have 1024 bright RGB LEDs arranged in a 32x32 grid on the front with 4mm grid spacing. On the back there is a PCB with two sets of dual IDC connectors (two input, two 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 panels require 13 digital pins (6 bit data, 7 bit control) and a good 5V supply, up to 4A per panel.

Comes with: a single 32x32 RGB panel, two IDC cables, a power cable, 4 mounting screws and mini-magnets (it appears these are often mounted on a magnetic base).

Keep in mind that these displays are 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. This display does best with a high speed, high RAM microcontroller like a SAMD21, SAMD51, ESP32, etc. 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.

Of course, we wouldn't leave you with a datasheet and a "good luck!" you will find a full wiring diagrams and working Arduino library code with examples from drawing pixels, lines, rectangles, circles and text. You'll get your color blasting within the hour! You'll need 13 digital pins, and 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 to handle it.
