Keyestudio LED dot matrix display module 16 * 16 unlimited cascading / 12864 compatible interfaces for arduino

The Keyestudio 16 x 16 LED dot matrix display module combines four 8 x 8 matrices into a single, versatile display for text and graphics. It is ideal for South African students, makers, and Arduino hobbyists looking to add clear visual feedback or custom animations to their electronics projects.

Four-in-one matrix design

This module integrates four 8 x 8 dot matrices to form a seamless 16 x 16 display area. It uses dynamic scanning across 16 cycling lines to display custom text, symbols, and graphics clearly.

Efficient line and column decoding

Line selection is managed by a 4-to-16 decoder made of two 74HC138 chips connected to the LED anodes. Column output is driven by two cascaded 74HC595 shift registers, converting serial data to parallel via SPI.

Plug-and-play interface compatibility

The display is fully compatible with the standard LCD12864 interface, allowing for quick, hassle-free connections. It operates on a standard DC 5V supply voltage, making it easy to integrate into existing setups.

Comprehensive Arduino and 51 MCU support

Get started quickly with the included wiki tutorial and rich code routines. The module comes with ready-to-use sample code for both Arduino and 51 single-chip microcontrollers.
