Huidu HD-D06 Wi-Fi LED controller for text and graphics
The HD-D06 is an asynchronous full-color LED control card for stored text, images, clocks and supported animation. It uses four HUB75E module outputs, Wi-Fi or USB program updates, and 128 MB onboard storage for offline playback.
Video playback is not supported. Choose content formats that match the D06 rather than assuming that a full-color controller can decode video files.

HD-D06 frequently asked questions
Can Huidu HD-D06 play video files?
No. The existing product information and D06 V2.0 specification explicitly exclude video playback. The card supports images, text, clocks, SWF/GIF animation and decorative effects instead.
What LED display size can the D06 control?
The listed control range is 1024 × 64 pixels, with maximum width 1024 and height 128. Do not treat both maximum dimensions as a guaranteed 1024 × 128 canvas; confirm the module layout and scan mode.
How do I update programs on the D06?
Use HDPlayer on a computer or LedArt on a mobile device through Wi-Fi, or update programs with a USB drive. The controller stores program files locally for offline playback.
How much storage does HD-D06 include?
It has 128 MB onboard program storage and supports expansion through USB storage. Confirm the drive and program compatibility rather than interpreting the older “unlimited” wording as an unlimited physical storage capacity.
Can D06 show temperature or adjust brightness automatically?
The product lists temperature/humidity and adaptive-brightness functions, with temperature and external-sensor connections in the V2.0 document. These functions require the appropriate compatible sensor accessories and configuration.
