{"product_id":"64x32-rgb-led-matrix-3mm-pitch","title":"64x32 RGB LED Matrix - 3mm pitch","description":"\u003cp\u003e\u003cspan\u003e2048 bright RGB LEDs arranged in a 64x32 grid on the front. On the back there are 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eRAM \u0026amp; Processor Requirements\u003c\/h3\u003e\n\u003cp\u003eKeep 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.\u003c\/p\u003e\n\u003cp\u003eYou'll need 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! These displays are technically 'chainable' - connect one output to the next input - as long as you have the RAM and CPU to handle it\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e","brand":"Gadgetcat LLC","offers":[{"title":"Default Title","offer_id":42851682123879,"sku":null,"price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0559\/8681\/5079\/files\/IMG-3468.jpg?v=1776879517","url":"https:\/\/gadgetcat.com\/products\/64x32-rgb-led-matrix-3mm-pitch","provider":"Gadgetcat LLC","version":"1.0","type":"link"}
