These panels are normally used to make video walls, here in New York we see them on the sides of busses and bus stops, to display animations or short video clips. We thought they looked really cool so we picked up a few boxes of them from a factory. They have \u003cstrong\u003e1024\u003c\/strong\u003e bright RGB LEDs arranged in a 32x32 grid on the front with\u003cstrong\u003e 4mm grid spacing\u003c\/strong\u003e. 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.\u003c\/p\u003e\u003cp\u003eThese 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!\u003cbr\u003e\u003cbr\u003eComes 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)\u003c\/p\u003e\u003cp\u003eKeep 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.\u003cbr\u003e\u003cbr\u003eOf course, we wouldn't leave you with a datasheet and a \"good luck!\" We have 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. \u003cstrong\u003eYou cannot use this size panel with an Arduino UNO (ATmega328) or ATmega32u4\u003c\/strong\u003e - you need a chip with more RAM!\u003c\/p\u003e\u003cp\u003eThese displays are technically 'chainable' - connect one output to the next input - as long as you have the RAM to handle it\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlease note!\u003c\/strong\u003e 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.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cp\u003eWe don't have a spec or datasheet at this time.
