An Arduino/ESP-IDF library for the ESP32, ESP32-S2, and ESP32-S3 that drives HUB75/HUB75E RGB LED matrix panels using hardware DMA for high refresh rates with low CPU overhead. It provides an Adafruit GFX-compatible drawing API, binary-code modulation for color depth, panel chaining, and CIE 1931 luminance correction.

Use cases

• drive HUB75 LED matrix panels with an ESP32
• display graphics on RGB LED matrix panels at high refresh rates
• chain multiple LED matrix panels into a larger display
• draw text and shapes on an LED matrix using Adafruit GFX
• build an LED matrix clock or sign with ESP32
• render animations on 64x64 or 64x32 LED panels
• control outdoor 1/4 scan LED panels with ESP32-S3

When to choose

• you are using an ESP32-family microcontroller with HUB75-connected LED panels
• you need high refresh rates without CPU-heavy bit-banging
• you want Adafruit GFX compatibility for easy drawing code
• you need to chain multiple panels into a larger virtual display

When to avoid

• you use WS2812/NeoPixel strips or other non-HUB75 LED hardware
• your project runs on non-ESP32 microcontrollers like AVR or STM32
• you need to drive unsupported panel driver chips not listed as working
• you want a plug-and-play solution without wiring and power supply considerations
