Huidu HD-R708 receiving card with 8 HUB75E outputs
The HD-R708 receives display data from a compatible Huidu sending device and distributes it to LED modules through eight HUB75E interfaces. It supports conventional driver ICs and most PWM ICs, with scan modes from static to 1/128 scan.
Module matching and screen configuration
Recommended loading differs by driver type: 128 × 512 pixels for conventional IC modules and 256 × 512 pixels for PWM IC modules. Match the module wiring, scan mode and cabinet layout before applying a configuration. The specification also lists full use of all eight ports for P1.667, P1.538 and P1.25 modules; verify the exact module configuration rather than selecting by pixel pitch alone.
Receiving cards can be arranged in the required screen sequence. Smart settings assist module configuration, while the onboard test function helps check display uniformity. The two Gigabit Ethernet ports are interchangeable for upstream and downstream connections.

Frequently asked questions
What is the HD-R708 loading capacity?
The specification recommends 128 × 512 pixels with conventional driver ICs and 256 × 512 pixels with PWM ICs. Choose the load according to the actual module, driver IC and scan configuration.
Does the R708 connect directly to LED modules?
Yes. It has eight HUB75E interfaces for LED module connections. Check the module pinout and scan configuration before connecting the ribbon cables.
Can the R708 play videos without a sending device?
The R708 is a receiving card. It works downstream of a compatible sending card, dual-mode player or VP-series video processor; it is not a standalone multimedia player.
Are its two Ethernet ports interchangeable?
Yes. The specification describes the two Gigabit Ethernet ports as interchangeable for connecting a sending card or another receiving card.
What supply voltage should I use?
The input range is DC 4.0–5.5 V. The manufacturer recommends a standard 5 V supply for stable operation.
