Huidu HD-C16H Asynchronous LED Controller
The Huidu HD-C16H combines LED content playback, sending and receiving in one full-color control card. Its 16 onboard HUB75E interfaces drive LED modules directly, while a Gigabit Ethernet output supports cascading with HD series receiving cards. It is intended for applications such as light-pole displays, entrance signs, vehicle screens and community information displays.
Choose the loading configuration carefully: the C16H alone supports 260,000 pixels; a system using cascaded receiving cards supports up to 650,000 pixels. Actual loading depends on interface use and module resolution. Video playback resolution is separate from the LED screen’s pixel capacity.
Control and Content Playback
Built-in 2.4 GHz Wi-Fi supports AP and STA modes, including simultaneous operation, and wireless control through the LedArt mobile app. Programs can be updated using USB or Ethernet. Optional 4G connectivity supports remote management through XiaoHui Cloud.
Supported content includes video, images, GIFs, text, animated text, colored fonts, documents, tables, clocks and timers. Playback supports one 4K stream, three 1080P streams, eight 720P streams or sixteen 360P streams.
Technical Specifications

Planning an HD-C16H Installation
Check the total screen pixel count, module resolution and HUB75E connections before choosing direct module connection or cascaded receiving cards. For a wide or tall display, check the loading restrictions in the specification rather than multiplying the maximum width and height. Confirm the optional HDMI board or 4G configuration if either is required for the installation.

Frequently Asked Questions
How many pixels can the HD-C16H control?
The card alone supports 260,000 pixels. With cascaded receiving cards, the total loading capacity is up to 650,000 pixels. Module resolution, interface use and screen dimensions affect the applicable limit.
Can the HD-C16H connect directly to LED modules?
Yes. It has 16 onboard HUB75E interfaces for direct module connection. Its Gigabit output also supports HD series receiving cards when a cascaded layout is needed.
Can I update the screen from a phone?
Yes. Built-in 2.4 GHz Wi-Fi supports wireless control with the LedArt app. AP and STA modes are supported, and the specification recommends operation within 15 m.
Does the HD-C16H include HDMI input?
HDMI input requires the optional adapter board. The stated maximum input is 1920 × 1080 at 60 Hz; confirm that the board is included in the required configuration.
Does 4K playback mean it can drive a 4K LED screen?
No. The stated one-stream 4K capability describes video playback. LED output remains subject to the standalone or cascaded pixel limits and the screen-loading restrictions above.
