{"product_id":"adafruit-4119","title":"Adafruit CharliePlex LED Matrix Bonnet, 8x16 Yellow LEDs, 4119","description":"\u003cp\u003eYou won't be able to look away from the mesmerizing patterns created by this Adafruit CharliePlex LED Matrix Display Bonnet. \u0026nbsp;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 - this is the yellow LED matrix.\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","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":53560455004488,"sku":"adafruit-4119","price":14.55,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/2250\/3638\/files\/4119-04.jpg?v=1784559247","url":"https:\/\/paradisetronic.com\/en\/products\/adafruit-4119","provider":"Paradisetronic.com","version":"1.0","type":"link"}
