Adafruit 15x7 CharliePlex LED Matrix Display FeatherWing - Red

You won't be able to look away from the mesmerizing patterns created by this Adafruit 15x7 CharliePlex LED Matrix Display FeatherWing. This 15x7 LED display can be paired with any of the Feather boards for a beautiful, bright grid of 105 charlieplexed LEDs. It even comes with a built-in charlieplex driver that is run over I2C.

We carry these FeatherWings in five vivid colors—this is the Red matrix. The I2C LED driver chip has the capability to PWM each individual LED in a 15x7 grid, allowing for beautiful LED lighting effects with minimal effort. Simply specify the LED you want to illuminate and its brightness, and it's all managed for you.

You get 8-bit (256 level) dimming for each individual LED. The IS31FL3731 chip is user-friendly and operates efficiently on 3.3V power. It includes enough RAM for eight separate frames of display memory, enabling you to set up multiple frames of an animation and switch them with a single command. Using I2C, it only occupies the SDA/SCL pins on your Feather and can share them with other I2C devices and sensors.

Our graphics library simplifies drawing shapes, text, and bitmaps, creating strikingly beautiful LED displays. Check out the tutorial for assembly instructions, CircuitPython and Arduino example codes, pinouts, schematics, and more!
