## When to use an 8×8 LED matrix?

8×8 LED MATRIX MODULE is used for various purpose; we can point a few: Case1: When the cost is of issue. LED MATRIX could be considered the cheapest of all DISPLAY devices present on market Case2: When there is a need for displaying ALPHABETS and CUSTOM characters.

## How many pins are in a LED matrix?

To understand the LED matrix internal structure, first, understand a simple LED. The LED has two pins that use DC power to give the output as a LIGHT. In this matrix, there are 8 numbers of rows and 8 numbers of columns.

## How many LEDs are in a bi color backpack?

Bi-Color 8×8 Matrix. This version of the LED backpack is designed for these bright and colorful square=pixeled 8×8 matrices. They have 64 red and 64 green LEDs inside, for a total of 128 LEDs controlled as a 8×16 matrix.

## Why are there 8 rows and 8 columns in LED matrix?
