Huidu HD-R716 is a high‑performance LED receiving card designed for large‑scale high‑resolution LED display systems, supporting both synchronous and asynchronous control modes. It features 16 onboard HUB75E interfaces, delivering 32 groups of RGB parallel data with a maximum loading capacity of 327680 pixels (512×640). For conventional IC modules, it supports 160×1024 or 256×640; for PWM IC modules, it reaches 320×1024, 256×1280 or 512×640.
Equipped with dual Gigabit Ethernet ports, HD-R716 enables stable daisy‑chain connection and redundant backup, supporting data transmission up to 80 meters via Cat5e/Cat6 cables. It supports scan modes from static to 1/128, compatible with common and most PWM driver IC modules. The card provides 256 to 65536 grayscale levels, ensuring smooth color gradients and high‑fidelity image reproduction.
It offers smart functions including visual connection indication, data group offset, row/column skipping, and module misalignment adjustment, ideal for irregular and creative LED screens. With DC 4.0–5.5V input and max 5W power consumption, it ensures reliable 24/7 operation in temperatures from -40°C to +80°C. Widely used in indoor/outdoor LED advertising walls, fine‑pixel video walls, stage backgrounds, command centers, and studio displays.
