Introducing the Adafruit LED Matrix Backpack – a simple and compact solution to add a bright, multiplexed LED display to your project without the hassle of complicated wiring.
With this backpack, you can control mini 8x8 LED matrices or a 4-digit 7-segment display using a single I2C interface. The display is driven by a MAX7219 driver chip, which handles all the multiplexing and power requirements. This makes it easy to create a small, dynamic display with minimal setup.
Key Features:
-
Bright, Ultra-Consistent LEDs: Utilizes constant-current drivers for ultra-bright, evenly colored displays.
-
Easy I2C Control: Simplify your setup with I2C connectivity for easy communication with your microcontroller.
-
Multiplexing & Address Selection: Supports up to four 8x8 matrices or eight 7-segment displays on a single I2C bus, with address-selection jumpers to manage multiple displays.
-
Built-in Clock: Handles multiplexing with a built-in clock, reducing the complexity of your wiring.
-
Dimming Control: 1/16 step display dimming for flexible brightness settings.
Included in the kit:
- Fully assembled and tested LED backpack with a pre-soldered 4-digit 0.56" tall yellow seven-segment display.
-
4-pin header for breadboard use (optional soldering required).
-
STEMMA QT connectors for easy, solderless connections, compatible with SparkFun Qwiic I2C connectors, enabling chaining with other sensors or accessories.
Also, enjoy a detailed tutorial and library provided by Adafruit, making it simple to get started in under 30 minutes. Whether you want to display images on an 8x8 matrix or show numbers on a 7-segment display, this backpack is the perfect solution for adding a clear, bright display to your project without the complexity.
