Adafruit CharliePlex LED Matrix Bonnet 8x16 Warm White LEDs
PRODUCT ID: 4122
You won't be able to look away from the mesmerizing patterns created by
this Adafruit CharliePlex LED Matrix Display Bonnet. This 16x8 LED display can
be placed atop any Raspberry Pi computer with a 2x20 connector, for a
beautiful, bright grid of 128 charlieplexed LEDs. It even comes with a built-in
charlieplex driver that is run over I2C.
We carry these Bonnets in a few vivid colors - this is the warm white LED matrix.
What is particularly nice about this Wing is the I2C LED driver chip has the ability
to PWM each individual LED in a 16x8 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 Pi and
can share those pins with other I2C devices and sensors.
Comes fully assembled, no soldering required, so you can plug it in
immediately. To program it, you'll use our CircuitPython library, which works
with Linux computers like Raspberry Pi. After a pip install, run some of the
examples to display simple graphics or text.
