NovaStar NV7516 receiving card for 16 HUB75E module connections
The NovaStar NV7516 provides 16 standard HUB75E interfaces and supports up to 32 groups of parallel RGB data. It is a receiving card for distributing controller data to LED cabinet modules. For selection, distinguish the physical cable connections from the total pixel load the card can process.
The values on this page follow the Chinese NV7516 specification V1.0.2, dated June 23, 2026. Source bit depth and module driver IC type determine the documented loading limit. Check the hardware revision, firmware and cabinet configuration before using these values in a replacement plan.
NV7516 pixel capacity at 8-bit and 10-bit
| Driver IC | 8-bit source | 10-bit source |
|---|---|---|
| PWM driver IC | 512 × 512 pixels | 512 × 256 pixels |
| Common driver IC | 512 × 384 pixels | 512 × 192 pixels |
Sixteen module interfaces do not multiply the card’s total pixel capacity. Select the row for the actual driver IC and the column for the source bit depth. The 60 Hz figure accompanies these loading conditions; it does not state the LED module refresh rate.
Board dimensions and power requirements
| HUB75E interfaces / RGB groups | 16 interfaces / up to 32 parallel groups |
|---|---|
| Input voltage | DC 3.8–5.5 V |
| Rated current / consumption | 0.5 A / 2.5 W |
| Board size | 91.5 × 145.6 × 19.3 mm |
| Net card weight | 101.9 g |
| Operating conditions | −20°C to +70°C; 10–90% RH, non-condensing |
Actual current and power vary with settings, environment and use. Check mounting positions, ribbon-cable routing and access to the power and Ethernet connections. Match the module pin assignments and scan mode to the working cabinet.
Image tuning with the correct supporting equipment
- Color management and grayscale: standard or custom color gamuts and 18bit+ support display adjustment. Pixel-level brightness and chroma calibration works with NovaStar’s calibration system.
- Cabinet consistency: quick dark/bright-line adjustment and multi-batch adjustment help tune seams and differences between cabinets or modules.
- Low latency: the one-frame value is specified at the receiving card for modules using driver ICs with built-in RAM. Other stages contribute their own latency.
- 3D and gamma: a supporting controller is required for 3D. Individual RGB gamma adjustment needs NovaLCT and a controller supporting that function.
- Rotation: 0°, 90°, 180° and 270° image rotation is documented.
Maintenance, mapping and backup paths
Data-group mapping and Mapping 1.1 help identify the module data layout and the controller, Ethernet-port and receiver numbers. Receiver temperature, voltage, bit-error and cable-disconnection counts support troubleshooting. With a cabinet LCD module, temperature, voltage and runtime information can be displayed locally.
Save firmware, receiver parameters and calibration files before replacing a board. Loop backup needs primary and backup cable connections between the controller and receivers. Dual program backup retains two firmware copies for recovery if an update becomes abnormal. Review the cable topology and maintenance files separately.
NV7516 selection and replacement questions
Is NV7516 a 32-connector receiving card?
No. It has 16 physical HUB75E interfaces and supports up to 32 parallel RGB data groups. Count the actual module cables when planning a cabinet.
Does it carry more pixels than NV7512 because it has more ports?
The referenced specifications list the same four loading limits for these two models. NV7516 has 16 HUB75E interfaces, while NovaStar NV7512 has 12. Select by the required connection layout as well as pixel loading and compatibility.
Can 18bit+ replace the source bit-depth check?
No. 18bit+ is an image-processing feature. The specification still lists separate maximum loads for 8-bit and 10-bit video sources and for PWM or common driver ICs.
What details help confirm a replacement?
