It features -- no surprise -- 117 RGB LEDs, each one 2x2mm in size, in a 13x9 grid with 3mm pitch spacing.\u003c\/p\u003e\n\u003cp\u003eUnlike the 8x8 dotstar grid, these are not NeoPixel or DotStar or other 'smart' RGB LEDs. Instead of having a lil chip in each LED, there's one large controller chip that handles all the PWM for you. The ISSI IS32FL3741 communicates over I2C and can set each LED element with 8 bit PWM for 24-bit color across the RGB elements, for beautiful color! There's an adjustable current driver so you can brighten or dim the whole display without losing color resolution.\u003c\/p\u003e\n\u003cp\u003eEach assembled board comes with the grid, four mounting holes, and the IS31FL3741 chip with all supporting circuitry. The board can run from 3.3 to 5V DC power and logic - powering from 5V is recommended since the green and blue LEDs look better with the extra headroom. Adafruit designed the PCB so you can tile the boards side-to-side if you desire, you'll just have to cut\/solder the jumpers on the bottom to change the I2C address: Up to 4 boards can share one I2C bus.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_IS31FL3741\" target=\"_blank\"\u003eUse Arduino\u003c\/a\u003e or \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_CircuitPython_IS31FL3741\" target=\"_blank\"\u003eCircuitPython\/Python to quickly set pixels\u003c\/a\u003e to any color you desire. Note that I2C makes this board very easy to wire up compared to our \"HUB75\"-style RGB LED Matrices \u003cem\u003ebut\u003c\/em\u003e that also makes the display slower because each pixel must be written over I2C. For a small display with simple animations, its fine - but if you want to do video or larger graphics we recommend upgrading to the HUB75 style.\u003c\/p\u003e\n\u003cp\u003eAdafruit made it easy for you to get some color right into your next project. The LED matrix and circuitry is soldered onto a custom-made PCB with two \u003ca href=\"\/en-eu\/collections\/stemma-qt\" target=\"_blank\"\u003eSTEMMA QT connectors\u003c\/a\u003e on the top, and are compatible with the \u003ca href=\"\/en-eu\/collections\/qwiic\" target=\"_blank\"\u003eSparkFun Qwiic\u003c\/a\u003e I2C connectors. This allows you to make solderless connections between your development board and the IS31FL3741 or to chain it with a wide range of other sensors and accessories using a \u003ca href=\"\/en-eu\/products\/jst-sh-cable-qwiic-stemma-qt-compatible\" target=\"_blank\"\u003ecompatible cable\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cp\u003eProduct Dimensions: 51.3mm x 39.0mm x 4.6mm \/ 2.0\" x 1.5\" x 0.2\"\u003c\/p\u003e\n\u003cp\u003eProduct Weight: 5.8g \/ 0.2oz\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":39475809615955,"sku":"ADA5201","price":14.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/5201-00.jpg?v=1653321070","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-is31fl3741-13x9-pwm-rgb-led-matrix-driver-stemma-qt-qwiic","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
