8x8 LED Dot Matrix 38mm

This 8x8 LED Dot Matrix is an array of 64 total LED lights, arranged in 8 columns and 8 rows, designed to meets strict ROHS standard. It is built intelligently with only 16 pins to minimize the amount of digital outputs needed from microprocessors, and works by connecting current through the rows and the ground through the columns – thus causing the LEDs to light up where the row and column meet. This, in conjunction with multiplexing at a high frequency, can provide a clear display of almost any kind of pixelated 8x8 image.

Typical Applications for the 8x8 LED Dot Matrix 38mm:

These 8x8 LED Dot Matrix 38mm displays are most commonly used to present scrolling text or numerical values like temperatures or small messages. They can also be installed in parallel and utilized together, which may require some extra programming and effort, but can double the size of the display. For beginner electronics enthusiasts, these can also be used for multiplexing experimentation.
