A C++ library (with Python bindings) for driving HUB75-style RGB LED matrix panels directly from Raspberry Pi GPIO pins, supporting multiple chained panels with up to 11-bit PWM per channel. It includes demo binaries and utility tools for displaying content on the panels.

Use cases

• drive an RGB LED matrix panel from a Raspberry Pi
• display scrolling text or images on LED panels
• build a LED matrix clock or info display
• chain multiple 64x64 LED panels on a Raspberry Pi
• render animations on HUB75 panels with 24-bit color
• create a Raspberry Pi LED sign

When to choose

• you have HUB75-style RGB LED panels and a Raspberry Pi
• you need high refresh rates and true 24-bit color via PWM
• you want a mature, well-documented C/C++ or Python API for LED matrices

When to avoid

• you use PWM-based LED panels, which need a different driver
• your project is not on Raspberry Pi hardware
• you need a plug-and-play application rather than a programming library
