The four tactile buttons can be used to switch between modes, as controls for simple games, or adjusting brightness.\u003c\/p\u003e\n\u003cp\u003eIt's possible to control the colour and brightness of each LED individually so you can use it to display animations, text, simple images, and more. Make a mini photo FX lamp, a smart status light for Zoom, use it to display colourful scrolling messages on your fridge, or just enjoy some pretty animations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA Raspberry Pi Pico is not included\u003c\/strong\u003e - click here if you'd like to buy one!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eYour Pico will need to have male headers soldered to it\u003c\/strong\u003e (with the pins pointing downwards) to attach to our add-on boards.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e16x7 matrix of RGB LEDs (112 total)\u003c\/li\u003e\n\u003cli\u003eIndividual colour\/brightness control of each LED\u003c\/li\u003e\n\u003cli\u003e4 x tactile buttons\u003c\/li\u003e\n\u003cli\u003ePre-soldered female headers for attaching to Pico\u003c\/li\u003e\n\u003cli\u003eCompatible with Raspberry Pi Pico.\u003c\/li\u003e\n\u003cli\u003eFully assembled\u003c\/li\u003e\n\u003cli\u003eNo soldering required (as long as your Pico has header pins attached).\u003c\/li\u003e\n\u003cli\u003eDimensions: approx 62mm x 25mm x 10mm (L x W x H, including headers and buttons)\u003c\/li\u003e\n\u003cli\u003eC\/C++ and MicroPython libraries\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eGetting started\u003c\/h2\u003e\n\u003cp\u003eThe labels on the underside of Pico Unicorn Pack will show you which way round to plug it into your Pico - just match up the USB port with the markings on the board.\u003c\/p\u003e\n\u003cp\u003eThe easiest way to get started with Pimoroni Pico add-ons is by downloading and copying the custom MicroPython firmware to your Pico.

The programmable IOs are so fast that we can achieve 14-bits of resolution instead of the 8-bits you usually get with LED drivers.\u003c\/p\u003e\n\u003cp\u003eWe use these extra bits of resolution to apply gamma correction to the colours displayed meaning that gradients are smooth and linear.\u003c\/p\u003e\n\u003cp\u003eThis means that the LEDs perform wonderfully through their full range of brightness rather than being poor at handling lower brightness levels. You don't really need to care about the details (though we think they are interesting!) as our software library just handles it all for you in the background.\u003c\/p\u003e","brand":"Pimoroni","offers":[{"title":"Default Title","offer_id":48620809027806,"sku":"qqn1787258015269","price":13.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/0705\/9422\/files\/pico-unicorn-pack_1.jpg?v=1787258023","url":"https:\/\/primewearfashion.shop\/products\/pico-unicorn-pack","provider":"My Store","version":"1.0","type":"link"}
