Keyestudio RJ11 EASY plug 8x8 LED Matrix Module( Address Select ) for Arduino

The Keyestudio RJ11 EASY plug 8x8 LED Matrix Module is a versatile display solution designed for students, educators, and makers working with Arduino. Driven by the HT16K33 chip, this module simplifies adding visual feedback and custom graphics to your projects. It is perfect for beginners looking for solderless, plug-and-play connections.

Efficient HT16K33 matrix driver

This module uses the HT16K33 chip to drive the 8x8 dot matrix display. By utilising I2C communication, it significantly reduces the number of microcontroller pins required for operation.

Solderless RJ11 easy plug interface

The four-pin interface is integrated into a crystal RJ11 plug. This allows you to quickly connect the module to a compatible control board using a standard RJ11 cable.

Adjustable I2C address selection

The board features three onboard DIP switches. You can toggle these switches to easily change the I2C communication address and avoid address conflicts.

Standard operating voltage range

The module operates reliably on a DC voltage range of 4.5V to 5.5V. This makes it fully compatible with standard 5V Arduino development boards.

Compact and lightweight design

Measuring just 56mm by 32mm by 18mm and weighing only 15.2g, this compact display fits easily into tight enclosures. It is ideal for portable or space-constrained robotics projects.
