HD-C16C asynchronous control for full-color LED screens
The Huidu HD-C16C stores and plays content for LED displays, with Wi-Fi app management and remote control through an Internet or LAN connection. Sending and receiving functions are integrated; HD-R series receiving cards can also be added for a larger screen configuration.
This model uses 10 HUB75E outputs. The related HD-C16 uses two 50-pin HUB connections, so the two versions should not be treated as interchangeable when checking module wiring.

Control range: the HD-C16C V0.1 specification dated April 8, 2021 lists 384 × 320 in its system-function table. The original marketing description also uses “120,000 pixels”; that does not equal 384 × 320 (122,880). Use the model-specific manual’s layout for configuration. The separate width and height limits do not describe a simultaneous 8192 × 512 screen area.
Updating programs and managing displays
Use HDPlayer on a computer or LedArt on a mobile device. Wi-Fi provides local wireless management, while the optional 4G module supplies an Internet connection for remote deployments. Multiple displays can be managed over the Internet or a LAN. The onboard relay supports remote power switching.
