This 16x8 LED display can be placed atop any Raspberry Pi computer with a 2x20 connector, for a beautiful, bright grid of 128 charlieplexed LEDs. It even comes with a built-in charlieplex driver that is run over I2C.\u003c\/p\u003e\n\u003cp\u003eWe carry these Bonnets in a few vivid colors -\u003cstrong\u003e this is the green LED matrix.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhat is particularly nice about this Wing is the I2C LED driver chip has the ability to PWM each individual LED in a 16x8 grid so you can have beautiful LED lighting effects, without a lot of pin twiddling. Simply tell the chip which LED on the grid you want lit, and what brightness and it's all taken care of for you. You get 8-bit (256 level) dimming for each individual LED.\u003c\/p\u003e\n\u003cp\u003eThe IS31FL3731 is a nice little chip - and it runs happily over 3.3V power. Inside is enough RAM for 8 separate frames of display memory so you can set up multiple frames of an animation and flip them to be displayed with a single command. Since it uses I2C, it takes up only the SDA\/SCL pins on your Pi and can share those pins with other I2C devices and sensors.\u003c\/p\u003e\n\u003cp\u003eComes fully assembled, no soldering required, so you can plug it in immediately. To program it, you'll use our CircuitPython library, which works with Linux computers like Raspberry Pi. After a pip install, run some of the examples to display simple graphics or text.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/nn9gQ4wUefg?start=326\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAdafruit CharliePlex LED Matrix Bonnet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Details\u003c\/h2\u003e\n\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cp\u003eProduct Dimensions: 65.0mm x 30.0mm x 6.8mm \/ 2.6\" x 1.2\" x 0.3\"\u003c\/p\u003e\n\u003cp\u003eProduct Weight: 8.2g \/ 0.3oz\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e\u003c\/ul\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":46375172014137,"sku":"ldw1787257887111","price":9.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0795\/9176\/8121\/files\/adafruit-charlieplex-led-matrix-bonnet---8x16-green-leds-discontinued_1.jpg?v=1787257896","url":"https:\/\/myoutfitstore.shop\/products\/adafruit-charlieplex-led-matrix-bonnet-8x16-green-leds-discontinued","provider":"My Store","version":"1.0","type":"link"}
