RGB LED Matrix Panel P4 80x40 HUB75

The RGB LED Matrix Panel P4 80x40 HUB75 by Waveshare is a full-color LED matrix module with a resolution of 80 × 40 pixels. It integrates a total of 3,200 individually controllable RGB LEDs with a 4 mm pixel pitch, enabling the display of text, colorful images, and animations. The brightness of the panel can be adjusted smoothly, allowing flexible use in various environments. The panel features two HUB75 connectors, one serving as data input and the other as data output, enabling cascading of multiple panels to create a larger display area. An external host controller is required for operation, as this is a pure display module without built-in control logic. Supported control platforms include ESP32, Raspberry Pi, Arduino, and STM32. Power supply is via a VH4 connector with 5V at a minimum of 4A, with a maximum power consumption of 20W. The viewing angle is at least 140°, ensuring good readability even from side angles. The panel operates in 1/20 scan mode and uses the 1R1G1B pixel format. Waveshare provides open-source development resources and example code for common platforms, making it easier to start your own projects.
