Description
The 8×16 LED Dot Matrix Display Board is a compact and versatile visual output module designed for microcontroller-based projects, electronic signage, and interactive displays. This board features 128 bright LEDs arranged in an 8-row by 16-column grid (8×16 pixels), providing a balanced resolution that is ideal for displaying alphanumeric characters, custom graphics, scrolling text, animations, and real-time data visualizations .
At the heart of this module is the AIP1640 driver chip, which is pre-soldered on the back of the PCB. This dedicated IC handles all the complex multiplexing and refresh timing internally, eliminating the need for constant microcontroller intervention and ensuring flicker-free display performance. The AIP1640 communicates with your microcontroller via a simple I2C-like two-wire interface, requiring only two I/O pins (SCL and SDA) to control all 128 LEDs .
The module includes a standard 4-pin PH2.54 connector and comes with a matching 4-Pin Dupont cable, making it easy to connect to development boards such as Arduino, ESP32, ESP8266, Raspberry Pi, micro:bit, STM32, and 8051-series microcontrollers . The 1.2mm PCB thickness provides durability while maintaining a lightweight form factor.
Color Options: This module is available in three single-color variants—Red, Green, and Yellow. Each variant offers bright, high-contrast illumination suitable for various applications. (Note: This is a single-color display; the color is fixed based on the variant you select.)
The module operates on a wide voltage range of DC 3.3V to 5V, making it compatible with both 3.3V logic (Raspberry Pi, ESP32) and 5V logic (Arduino) systems without requiring level shifters . Four 2.2mm mounting holes at the corners allow for secure installation in enclosures, panels, or custom projects.
Whether you need to build a scrolling message board, create a real-time sensor data display, design a custom scoreboard, add visual feedback to your IoT project, or teach programming concepts in an educational setting, this 8×16 LED Dot Matrix Display Board delivers reliable, bright, and easy-to-control performance in a compact package.
