This 15x7 LED display can be paired with any of Adafruits 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.

Adafruit produces these FeatherWings in five vivid colors - this is the Blue matrix.

What is particularly nice about this Wing is the I2C LED driver chip has the ability to PWM each individual LED in a 15x7 grid so you can have beautiful LED lighting effects, without a lot of pin twiddling. Simply tell the chip which LED on the grid you want lit, and what brightness and it's all taken care of for you. You get 8-bit (256 level) dimming for each individual LED.

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

Specification:

  • Uses I2C address 0x74 or 0x77
  • Product Dimensions: 51.0mm x 23.0mm x 3.0mm / 2.0" x 0.9" x 0.1"
  • Product Weight: 3.8g / 0.1oz
