BUT ARE THEY 3 WATTS BRIGHT? No! They are not! That's why you need a \u003cstrong\u003ePixie\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThese chainable smart LEDs are not only super-smart, they are ridonkulously bright with 3W total, compared to 0.2W of a 'standard' NeoPixel. Designed by Ytai Ben-Tsvi, these are the ultimate in LEDs.\u003c\/p\u003e\n\u003cp\u003eEach Pixie not only contains that aforementioned 3W LED, it also has a Microchip PIC microcontroller. You send it the color you want to appear at standard 115200 baud (1 byte per color). You can send a longer string of pixel data and it will 'forward' along the messages so you can chain them like a shift register. You only have to send the data once per color change. Once set, the microcontroller does all the PWM handling for you.\u003c\/p\u003e\n\u003cp\u003eYou do have to send it data every 2 seconds at a minimum (as a protection against the bright and hot LEDs staying 'stuck on', they will eventually timeout if no updates are received). 1 second updates (or faster!) is best.\u003c\/p\u003e\n\u003cp\u003eSince the Pixie uses so much power, there's a risk of the LED heating up so much it damages itself and\/or the microcontroller. That's why Ytai added a temperature cut-off. When the PIC detects that the Pixie's temperature is too high, it turns off the LED until it gets back down to a reasonable level.\u003c\/p\u003e\n\u003cp\u003eEach Pixie comes fully assembled, with big pads for power wires (don't forget, we're talking about max 1 Amp per Pixie!) and mounting holes on the sides that fit M2 size screws. You'll also need thick wires to power each Pixie and a microcontroller that can send 115,200 baud 8N1 data to the Pixie (on its own, it will not do anything, you must send it data for it to light up).\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/pixie-3-watt-smart-chainable-led-pixels\/\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCheck the tutorial for more information including code, schematics, libaries, pinouts \u0026amp; more!\u003c\/a\u003e Our Arduino library is easy to use, has the same API you're used to with our NeoPixel library, and will get you blasting ROYGBIV in 5 minutes or less.\u003c\/p\u003e\n\u003cstrong\u003eTECHNICAL DETAILS\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/www.adafruit.com\/images\/product-files\/2741\/PIC12LF1571-2.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003ePIC12(L)F157X Datasheet\u003c\/a\u003e - 8-bit PIC microcontrller processor used\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"http:\/\/www.adafruit.com\/datasheets\/irlml2060pbf.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eIRLML2060 Datasheet\u003c\/a\u003e - Power transistor for each RGB channel\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.adafruit.com\/images\/product-files\/2530\/FD-3RGB-Y2.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e3W RGB LED Datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eWeight: 2g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Dimensions: 24.1mm x 19.7mm x 8.2mm \/ 0.9\" x 0.8\" x 0.3\"\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":8204687169,"sku":"ADA2741","price":14.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/2741-02.jpg?v=1447081679","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/pixie-3w-chainable-smart-led-pixel","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
