HUB75

HUB75 refers to a common interface standard used for connecting LED matrix panels, particularly in DIY electronics and professional display applications. It's a flexible and widely adopted protocol that simplifies the process of driving large LED displays. The HUB75 interface typically uses a 16-pin connector and transmits data serially along with control signals.

The standard specifies a set of signals including clock, data, latch, and output enable. These signals are crucial for synchronizing the data transfer and refreshing the LEDs on the matrix. Different types of LED panels, such as those with 32x32 or 64x32 pixel counts, can be driven using HUB75. The protocol allows for multiplexing, where a single controller can manage multiple panels by rapidly switching between them.

Libraries and development boards, like those based on Arduino or Raspberry Pi, often support the HUB75 interface. This makes it accessible for hobbyists and developers to create custom LED signage, visualizers, or interactive art installations. The simplicity and widespread support of HUB75 have made it a de facto standard for many LED matrix projects. Its adaptability allows for scaling up displays by daisy-chaining multiple panels together, creating larger and more complex visual outputs.
