NEW GUIDE: Adafruit IS31FL3741 #AdafruitLearningSystem #Adafruit @adafruit
Add a splash of color to your project!
Add a ton of RGB LEDs to a project you’re working on, with this adorable IS31FL3741 13×9 RGB LED matrix breakout. It features — no surprise — 117 RGB LEDs, each one 2x2mm in size, in a 13×9 grid with 3mm pitch spacing. These are not NeoPixel or DotStar or other ‘smart’ RGB LEDs. Instead of having a li’l 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. It comes complete with STEMMA QT connectors making getting started with it as simple as plugging it in!
The Adafruit IS31FL3741 guide has everything you need to get started with this board. There’s an overview, detailed pinouts page, downloads resources and examples in both CircuitPython and Arduino.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
