Huidu HD-R5S Plus receiver card overview
The Huidu HD-R5S Plus is a compact LED display receiving card with two 120-pin HUB connectors. It receives data from a compatible Huidu sending device and drives LED modules through the cabinet’s interface design. Its stated control range is up to 512 × 512 pixels per card. Plan the actual load around the LED module, scan mode, interface allocation and refresh requirements rather than treating the maximum pixel count as a universal operating target.

Display setup and features
- Module support: Designed for conventional LED driver chips and mainstream PWM chip modules. Confirm the driver IC, scan mode and HUB pinout before ordering.
- Flexible mapping: Supports module wiring setup, row and column adjustments, data group exchange and data group offset for cabinet configuration.
- Image tuning: Supports grayscale adjustment, RGB gamma settings and point-by-point brightness and color correction when used with a compatible correction workflow.
- Maintenance: Includes display test functions and receiver-card temperature and voltage monitoring. Configuration backup and receiver-card redundancy depend on the complete system setup.
Compatibility and installation notes
Use the HD-R5S Plus with a compatible Huidu sending card, dual-mode playback box or video processor. Check the exact 120-pin connector mapping, LED module resolution, scan mode, power requirements and software configuration against your cabinet design. The manufacturer’s stated control range is a maximum; achievable capacity can vary with the module and output arrangement. For a project-specific match, contact us with your module model, cabinet resolution and controller model.
Frequently asked questions
How many pixels can one HD-R5S Plus control?
Huidu lists a maximum control range of 512 × 512 pixels. Confirm the practical load for your module and wiring before deployment.
Which scanning modes does it support?
Huidu lists support from static through 1/128 scan. The module’s driver and wiring must also be compatible.
Is the HD-R5S Plus the same as the HD-R5S?
No. Huidu lists them as separate models with different maximum control ranges; verify the exact card marking when replacing a receiver card.
