Keyestudio Red color common cathode I2C 8*8 LED dot Matrix module HT16K33 for arduino

The Keyestudio Red 8x8 LED Dot Matrix Module is an easy-to-use display solution designed for Arduino projects. Driven by the HT16K33 chip, it allows students, educators, and makers to display custom graphics and characters with minimal wiring. This module is ideal for anyone looking to add a vibrant visual output to their robotics or coding projects.

Streamlined I2C control

Controlling a 64-LED matrix usually requires 16 pins, but this module uses the HT16K33 driver chip to run everything over a simple I2C interface. This significantly reduces the number of I/O ports required on your microcontroller.

Consistent colour and dimming

The backpack uses constant-current drivers to deliver ultra-bright, consistent red colour across all 8x8 LEDs. It also supports 1/16 step display dimming, giving you precise control over the display brightness.

Compact backpack design

Traditional driver setups like the MAX7219 require extensive wiring and take up valuable space on your breadboard. This integrated matrix backpack eliminates the clutter, offering a neat, space-saving solution for your projects.

Power and frequency specifications

The module operates on a 5V input voltage with a rated input frequency of 400kHz. It has an input power rating of 2.5W and an input current of 500mA, making it highly compatible with standard Arduino development boards.

Simple connection and expansion

With easy access to I2C communication pins, this common cathode module is simple to connect and highly expandable for advanced experiments. Makers and students can quickly get started using the available Arduino software and wiki tutorials.
