Description
The 7×5 LED Dot Matrix Display is a compact green LED alphanumeric display designed for electronics, Arduino, microcontroller, and DIY projects. It features a 5-column × 7-row matrix, providing 35 individual LED dots that can be controlled to create letters, numbers, symbols, and custom patterns.
This display uses an X-Y matrix configuration, making it suitable for projects where multiple LEDs need to be controlled through rows and columns. Its through-hole construction and standard 2.54mm pin spacing make it easy to solder onto PCBs and integrate into electronic circuits.
The LED matrix features a grey face with green LEDs and provides clear ON/OFF contrast, making displayed characters easy to see. Multiple displays can also be arranged together for applications requiring multiple characters or larger custom displays.

X-Y Matrix Configuration
The display uses an X-Y row and column selection method, allowing individual LED dots to be controlled through the matrix connections. This makes it possible to create custom letters, numbers, symbols, and simple graphical patterns using a suitable microcontroller.
The pin configuration can vary between different LED matrix models. Therefore, always check the pinout of the specific display before connecting it to your circuit.
Easy PCB Installation
The through-hole package makes this 7×5 LED matrix easy to install on PCBs and prototype boards. Its 2.54mm pin spacing is commonly used in electronic components, making soldering and circuit integration straightforward.
Compact Alphanumeric Display
Despite its compact size, the 5×7 matrix provides enough resolution to create recognizable alphanumeric characters. The green LEDs and grey face provide good visual contrast for indicators, counters, custom displays, and other electronic applications.
