The ultra-bright LEDs are \u003cstrong\u003every visible\u003c\/strong\u003e, and the units are small enough to plug into a breadboard! The LEDs are contained inside the plastic body in an 8x8 matrix. There are 16 pins on the side, 8 on each, with 0.1\" spacing so you can easily plug it into a breadboard with one row on each side for wiring it up.\u003c\/p\u003e\n\u003cp\u003eThis dot matrix requires an IC to run, and the display is in a grid so you'll need a 1:8 multiplex to control it. You can run it with a MAX7219 which does the multiplexing for you.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eColour: Red (630nm)\u003c\/li\u003e\n\u003cli\u003eLuminous Intensity: 30mcd\u003c\/li\u003e\n\u003cli\u003eDC Forward Current: 20mA\u003c\/li\u003e\n\u003cli\u003eForward Voltage Range: 1.8 - 2.6V\u003c\/li\u003e\n\u003cli\u003eLong operational life\u003c\/li\u003e\n\u003cli\u003eLow power dissipation\u003c\/li\u003e\n\u003cli\u003eDimensions 31.75 x 31.75 x 8mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eTutorials\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eArduino - Controlling an Led matrix or 7-segment displays with the MAX7219\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eDriving a LED matrix from a Netduino one more time: The Right Way\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eUsing a MAX7219\/MAX7221 LED display driver with a Netduino\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ModMyPi","offers":[{"title":"Default Title","offer_id":48624048144602,"sku":"hgj1789680933000","price":4.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/small-8x8-dot-matrix-ultra-bright---red-discontinued_1.jpg?v=1789680936","url":"https:\/\/memoryfoamwear.shop\/products\/small-8x8-dot-matrix-ultra-bright-red-discontinued","provider":"My Store","version":"1.0","type":"link"}
