What Is a Matrix Board?
A matrix board is an electronic circuit board where LEDs, switches, and other components are arranged in a grid pattern. It is utilized across various fields, including electronics prototyping, education, art installations, and industrial equipment, due to its versatility and cost-effectiveness.
The operation of a matrix board hinges on three primary elements: components such as LEDs and switches, driver ICs, and a microcontroller (MCU). The MCU orchestrates the lighting patterns of the LEDs and the input states of the switches according to specific programming, whereas the driver ICs are responsible for providing power to the LEDs or switches and reading their states based on these directives.
Noteworthy for their adaptability, matrix boards enable the creation of complex displays and inputs by augmenting the number of LEDs or switches. This flexibility, combined with their ability to execute diverse functions through programming and their relative affordability, underscores their broad applicability and appeal.
