Get ready to be captivated by the amazing patterns of the Adafruit 15x7 CharliePlex LED Matrix Display FeatherWing in vibrant green. This 15x7 LED display pairs perfectly with any of our Feather boards, creating a beautiful and bright grid of 105 charlieplexed LEDs. It comes with a built - in charlieplex driver that operates via I2C. We offer these FeatherWings in five vivid colors, and this one is the eye - catching green matrix. The I2C LED driver chip is a real gem. It can PWM each individual LED in the 15x7 grid, giving you gorgeous LED lighting effects without the hassle of pin management. You can simply tell the chip which LED to light and at what brightness, and it takes care of the rest. Each LED has 8 - bit (256 - level) dimming. The IS31FL3731 chip runs smoothly on 3.3V power. It has enough RAM for 8 separate frames of display memory, allowing you to set up multiple animation frames and switch them with a single command. Since it uses I2C, it only takes up the SDA/SCL pins on your Feather and can share these pins with other I2C devices and sensors. Our graphics library makes it a breeze to draw shapes, text, and bitmaps for truly stunning LED displays. Check out the tutorial for assembly, CircuitPython and Arduino example code, pinouts, schematics, and more!




Using this Adafruit 15x7 CharliePlex LED Matrix Display FeatherWing is easy. First, pair it with your Feather board. Connect it using the I2C interface which only uses the SDA/SCL pins. The built - in charlieplex driver will start working right away. To create lighting effects, use our graphics library. You can draw shapes, text, or bitmaps with just a few steps. When you want to set up an animation, use the display memory. There's enough space for 8 frames, and you can switch between them with a single command. As for brightness, you can control each individual LED easily. Just tell the chip which LED to light and how bright you want it. Remember to use a 3.3V power supply for the IS31FL3731 chip to keep it running smoothly. When it comes to maintenance, keep it in a dry and clean place. Avoid touching the LEDs directly to prevent damage. If you have any questions, refer to the tutorial which has all the assembly instructions, example code, pinouts, and schematics.
