We’ve been using the IS31FL3731 for a while to do monochromatic LED driving/dimming. But for RGB LED driving, we need moar channels! So we’re trying out the IS31FL3741, which can handle an astonishing 351 individually-dimmable LEDs in 39×9 matrix. Divide by three for RGB LEDs, and you’ve got a 13×9 24-bit color display, all controllable over I2C! Next we’ll design a STEMMA QT breakout… video.

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.
