Product details

You won't be able to look away from the fascinating patterns created by this Adafruit 15x7 CharliePlex LED Matrix Display FeatherWing. This 15x7 LED display can be combined with any of our Feather boards and features a beautiful, bright grid of 105 Charlieplex LEDs. It even comes with a built-in Charlieplex driver that operates via I2C.

What’s particularly nice about this Wing is the I2C LED driver chip, which has the ability to control each individual LED in a 15x7 grid using PWM. This allows you to create beautiful LED lighting effects without using many pins. Simply tell the chip which LED on the grid you want to illuminate and at what brightness, and it will handle everything for you. You get 8-bit (256 levels) for each individual LED.

The IS31FL3731 is a nice little chip and runs happily on 3.3V power. Inside, it has enough RAM for 8 separate images of the screen memory, so you can set up multiple frames of an animation and display them with a single command. Since it uses I2C, it only requires the SDA/SCL pins of your Feather and can share these pins with other I2C devices and sensors.

* Product dimensions: 51.0 mm x 23.0 mm x 3.0 mm
