Keyestudio 8*8 LED Dot Matrix Module( Address Select) for Arduino

The Keyestudio 8x8 LED Dot Matrix Module is a compact, easy-to-use display designed to add visual feedback, custom characters, and simple animations to your microcontroller projects. Driven by the efficient HT16K33 chip, it is perfect for South African students, makers, and hobbyists looking to expand their Arduino builds without exhausting available pins.

Efficient HT16K33 driver chip

This module utilises the HT16K33 driver chip to manage the 8x8 dot matrix, significantly reducing the processing load on your microcontroller. It handles the LED multiplexing automatically, allowing you to focus on coding your custom graphics.

Resource-saving I2C communication

By communicating over a simple I2C interface, this module only requires two data pins on your development board. This leaves your other digital and analogue pins free for sensors, actuators, and other project components.

Adjustable I2C address selection

Equipped with three onboard DIP switches, the module allows you to easily toggle and select different I2C communication addresses. This makes it simple to connect multiple matrix displays to the same bus without address conflicts.

Simple jumper wire connections

The module features a standard 4-pin header with a 2.54mm pin pitch, making it fully compatible with standard breadboards and jumper wires. Connecting it to your control board is straightforward and secure.

Standard operating voltage

Designed to run on a DC 4.5V to 5.5V power supply, this module integrates seamlessly with standard 5V Arduino boards. It provides bright, consistent LED illumination without requiring external power regulators.

Compact physical dimensions

With a footprint of 52mm by 34mm by 11mm and a weight of just 13.2g, this lightweight module easily fits into custom enclosures. It is an excellent choice for wearable electronics, small robots, and desktop gadgets.
