{"product_id":"adafruit-rgb-matrix-shield-for-arduino","title":"Adafruit RGB Matrix Shield for Arduino","description":"\u003cp\u003eRGB matricies are dazzling, with their hundreds or even \u003cem\u003ethousands\u003c\/em\u003e of individual RGB LEDs. Compared to NeoPixels, they've got great density, power usage and the price-per-LED can't be beat. But...(isn't there always a \u003cem\u003ebut\u003c\/em\u003e?) You need to use a special library to control them and they require a bunch of wires to be plugged in. Tougher than a single-wire connection for sure.\u003c\/p\u003e\n\u003cp\u003eIf you've got an Arduino-compatible board, with an ATmega328p chip (like the \u003ca href=\"\/en-eu\/products\/adafruit-metro-328-without-headers-atmega328\" target=\"_blank\"\u003eMetro 328\u003c\/a\u003e) or SAMD21 (like the \u003ca href=\"\/en-eu\/products\/adafruit-metro-m0-express-designed-for-circuitpython-atsamd21g18\" target=\"_blank\"\u003eMetro M0\u003c\/a\u003e) or even SAMD51 (like the \u003ca href=\"\/en-eu\/products\/adafruit-itsybitsy-m4-express-featuring-atsamd51\" target=\"_blank\"\u003eMetro M4\u003c\/a\u003e) this shield will make usage a snap! A little light soldering to attach the headers, connector and terminal block and you're ready to rock. Plug it onto your microcontroller board, and you'll be able to attach any RGB matrix with ease. This shield just takes care of the wiring for you!\u003c\/p\u003e\n\u003cp\u003eFor 800mA or less power usage on the matrix you can even 'borrow' the 5V power from the Arduino's regulator. This isn't good for projects where you have a lot of LEDs on at once but for scrolling text and light LED usage it will make wiring even easier because you dont need a separate power adapter. Of course, if you need 1 Amp or more, just use the 2x8 connector for data and use a separate 5V 2A or 5V 4A wall adapter directly to the panel.\u003c\/p\u003e\n\u003cp\u003eNote that this shield is just a wiring adapter, if you have a Metro 328 you can only use 16x32 or possibly 32x32 matrices before you run out of RAM. For big panels, use a Metro M0 or M4 - those will work best thanks to their enormous RAM.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note Adafruits Arduino library only supports 32-pixel tall matrices, so don't try using a 64x64 matrix, it doesn't work!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/32x16-32x32-rgb-led-matrix\/connecting-using-rgb-matrix-shield\" target=\"_blank\"\u003eCheck out the guide for all the details!\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cp\u003eShield Dimensions (unassembled): 68.5 x 53.2 x 1.6mm\u003c\/p\u003e\n\u003ch2\u003eNotes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eYou'll need to assemble the shield once you get it, please see the link to the guide above for information on assembly and soldering.\u003c\/li\u003e\n\u003cli\u003eThis item is just the shield and does not include any LED matrices.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":12528737943635,"sku":"ADA2601","price":6.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/2601.jpg?v=1529511386","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-rgb-matrix-shield-for-arduino","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
