NovaStar NV3210 receiving card with 10 HUB320F connectors
The NovaStar NV3210 connects LED modules through ten standard HUB320F connectors. It supports up to 40 groups of RGB real-pixel data, 40 groups of 3-LED sub-pixel data, or 30 groups of 4-LED sub-pixel data. Match the module architecture and pin assignments before selecting a replacement.
This reference uses NV3210 Specifications V1.1.1, dated October 22, 2024. The maximum pixel load varies with the controller family, video source bit depth and driver IC. Use the relevant combination below and confirm the installed hardware revision and firmware.
NV3210 loading with M3 and COEX controllers
| Source | PWM driver IC | Common driver IC |
|---|---|---|
| 8-bit | 512 × 512 | 512 × 384 |
| 10-bit | 512 × 384 | 256 × 384 |
| 12-bit | 512 × 384 | 256 × 384 |
| Source | PWM driver IC | Common driver IC |
|---|---|---|
| 8-bit | 512 × 512 | 512 × 384 |
| 10-bit | 512 × 512 | 512 × 384 |
| 12-bit | 512 × 384 | 256 × 384 |
For example, a 10-bit source with PWM driver ICs has a documented limit of 512 × 384 with M3, versus 512 × 512 with COEX. The 60 Hz loading condition is separate from the LED module refresh rate. Confirm usable loading for other system arrangements.
NV3210 electrical and physical specifications
| Module connectors | 10 HUB320F |
|---|---|
| RGB real-pixel / 3-LED sub-pixel | Up to 40 data groups in either mode |
| 4-LED sub-pixel data | Up to 30 groups |
| DC input | 3.8–5.5 V |
| Rated current / power | 0.5 A / 2.5 W |
| Dimensions / net card weight | 146.0 × 91.5 × 19.2 mm / 99.5 g |

Actual current and power consumption vary with settings, usage and environment. Verify mounting positions, power access and the correct module pin diagram for the selected real-pixel or sub-pixel mode.

HDR, calibration and image adjustment
V1.1.1 lists HDR10 with SMPTE ST 2084 and ST 2086, plus HLG support. Check the source and controller signal chain for the intended HDR workflow. Color management supports standard and custom gamuts; 18bit+, seam adjustment and multi-batch adjustment provide image-tuning functions.
Pixel-level brightness and chroma calibration works with NovaStar’s calibration system. Individual RGB gamma adjustment requires NovaLCT and a supporting controller; 3D requires a controller supporting 3D. Image rotation is documented in 90° increments. The one-frame receiver latency condition requires module driver ICs with built-in RAM.
Module flash functions and recovery options
Automatic module calibration uses calibration coefficients stored in module flash memory. Module auto light-up also requires a flash-equipped module and dedicated firmware. Confirm these prerequisites before relying on automatic behavior after a module replacement.
Mapping 1.1 helps trace receiver locations and connections. Temperature, voltage and bit-error monitoring assist diagnosis; firmware and parameter readback help retain maintenance files. Dual NCP backup, configuration-parameter backup and dual program backup address stored files, settings and firmware. Loop backup instead requires primary and backup cable paths between the controller and receivers.
NV3210 selection questions
Is HUB320F interchangeable with HUB75E?
Confirm the actual module interface and pin assignments first. NV3210 specifies HUB320F. A similar board size or pixel capacity does not establish compatibility with a HUB75E cabinet.
Can I use one maximum-resolution number for every controller?
No. Use the M3 or COEX table, then choose the source bit depth and driver IC type. In particular, the documented 10-bit capacities differ between these controller families.
Will every replacement module light up automatically?
That feature requires a module with flash memory and dedicated firmware. Check the stored configuration and firmware support before replacing a module.
What should I provide for a compatibility check?
Contact EagerLED with board and module-connector photos, controller model, source bit depth, driver IC, scan mode and cabinet pixel dimensions. Compare other LED receiving cards only after confirming these requirements.
