This disk is chock full of *255* Dotstar LEDs and it's BRIGHT! The \u003cstrong\u003eDotstar RGB LED Disk\u003c\/strong\u003e is sprinkled with digitally-addressable LEDs, comes on a white PCB with two 4 pin JST-SM connectors already soldered to it so it's ready to rock straight out of the box.\u003c\/p\u003e\u003cp\u003eThese are the same integrated LEDs that are used in our new fancy DotStar strips. This tiny 5050 (5mm x 5mm) SMD LED is the most compact way possible to integrate multiple bright LEDs to a design. Rather than NeoPixels, this disk uses DotStar LEDs, which use a 2-wire protocol that is less timing-specific and has high-frequency PWM for smoother color blending.\u003c\/p\u003e\u003cp\u003eLike NeoPixels, DotStar LEDs are 5050-sized LEDs with an embedded microcontroller \u003cstrong\u003einside the LED\u003c\/strong\u003e. You can set the color\/brightness of each LED to 24-bit color (8 bits each red green and blue). Each LED acts like a shift register, reading incoming color data on the input pins, and then shifting the previous color data out on the output pin. By sending a long string of data, you can control an infinite number of LEDs. The PWM is built into each LED-chip so once you set the color you can stop talking to the disk and it will continue to PWM all the LEDs for you\u003c\/p\u003e\u003cp\u003eAnother nice thing about DotStars is their high PWM rate. You only have to set the 24-bit color data for each pixel LED once, and then the LED+built-in-chip will handle the PWMing of the red, green and blue. On NeoPixels, this PWM rate happens 400 Hz, which works well but is noticably at lower brightnesses and if the strip is moving in any way. DotStars have a 20 KHz PWM rate, so even when moving the disk around, you won't see the pixelation, the color blending is very smooth.\u003c\/p\u003e\u003cp\u003eYou'll need \u003cem\u003ea lot\u003c\/em\u003e of power to fully light up this disk, so be sure to pick of a 5V 10A power supply!\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWe have a tutorial showing wiring, power usage calculations, example code for usage, etc. Please check it out!\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: Shipping weight reflects UPS' new dimensional weight regulations.\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\u003cul\u003e\n\u003cli\u003eAPA102C Datasheet\u003c\/li\u003e\n\u003cli\u003eDotstar RGB LED Disk Datasheet\u003c\/li\u003e\n\u003cli\u003eDisk Diameter: 242mm\u003c\/li\u003e\n\u003cli\u003eDisk Thickness: 3mm\u003c\/li\u003e\n\u003cli\u003eWeight: 187g\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":48623656927450,"sku":"hvz1789674823118","price":112.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/dotstar-rgb-led-disk---240mm-diameter-discontinued_1.jpg?v=1789674827","url":"https:\/\/memoryfoamwear.shop\/products\/dotstar-rgb-led-disk-240mm-diameter-discontinued","provider":"My Store","version":"1.0","type":"link"}
