Get ready to be captivated by the amazing patterns of the Adafruit 15x7 CharliePlex LED Matrix Display FeatherWing in blue. This 15x7 LED display pairs perfectly with any Feather board, creating a bright and beautiful grid of 105 charlieplexed LEDs. It comes with a built - in charlieplex driver that operates over I2C. We offer these FeatherWings in five vivid colors, and this one is the stunning blue matrix. The I2C LED driver chip is a real gem. It can PWM each individual LED in the 15x7 grid, allowing you to create beautiful lighting effects without complex pin management. Just tell the chip which LED to light and at what brightness, and it'll handle everything. You get 8 - bit (256 - level) dimming for each LED. The IS31FL3731 chip runs smoothly on 3.3V power. It has enough RAM for 8 separate frames of display memory, enabling you to set up animations and switch between frames 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 eye - catching LED displays. Check out the tutorial for assembly instructions, CircuitPython and Arduino example code, pinouts, schematics, and more!
Using the Adafruit 15x7 CharliePlex LED Matrix Display FeatherWing is easy. First, pair it with your Feather board. It connects using the I2C interface, which only takes up the SDA/SCL pins on your Feather. You can also share these pins with other I2C devices and sensors. Our graphics library simplifies the process of creating LED displays. You can draw shapes, text, and bitmaps to make your display look really cool. To control the LEDs, use the built - in charlieplex driver. Just tell the chip which LED you want to light and at what brightness. It supports 8 - bit (256 - level) dimming for each LED. You can even create animations by setting up multiple frames of display memory. When it comes to power, the chip runs on 3.3V. For assembly instructions, CircuitPython and Arduino example code, and more details, check out the tutorial. As for maintenance, keep the display clean and avoid exposing it to extreme temperatures or moisture. If you notice any issues, refer to the troubleshooting section in the tutorial.
