NovaStar MRV412-S receiving card for 12 HUB75E connections
The NovaStar MRV412-S distributes display data to LED modules through 12 standard HUB75E connectors. It supports up to 24 groups of parallel RGB data. When selecting a receiver for a cabinet, check both the pixel load and the module-cable layout rather than choosing by resolution alone.
The values below follow MRV412-S Specifications V1.0.0, dated September 18, 2026. They describe this model and its documented conditions. Confirm the hardware revision, firmware, driver IC and existing cabinet configuration before ordering a replacement.
MRV412-S specifications
| PWM driver IC load | Up to 512 × 512 pixels at 60 Hz with an 8-bit source |
|---|---|
| Common driver IC load | Up to 512 × 384 pixels at 60 Hz with an 8-bit source |
| Module connections | 12 HUB75E connectors |
| Parallel RGB data | Up to 24 groups |
| DC input | 3.8–5.5 V |
| Rated current / power | 0.4 A at 4.2 V / 1.68 W |
| Dimensions / card weight | 91.5 × 144.0 × 19.3 mm / 93.5 g |
| Operating conditions | −20°C to +70°C; 10–90% RH, non-condensing |
Actual power consumption varies with settings and use. The 60 Hz values accompany the pixel-loading limits; they should not be presented as the LED module’s refresh rate. For other source formats or module arrangements, confirm the usable load separately.
Match the receiver to the cabinet
Record the module driver IC, scan mode, number of module connections and total cabinet width and height in pixels. Compare the HUB75E assignments and mounting drawing with the existing installation. Back up the working receiver parameters and calibration files before making changes.
For a different connector count, you can compare the NovaStar MRV416-S with 16 HUB75E connectors. Similar model names and shared features do not establish a direct replacement; check the wiring and configuration for the selected card.
Understand the image-processing requirements
The specification lists color management, 18bit+, pixel brightness and chroma calibration, seam adjustment and multi-batch adjustment. Calibration works with NovaStar’s calibration system. RGB gamma adjustment requires NovaLCT and a controller supporting the function.
Low latency is enabled by default. The documented one-frame value is at the receiving card and applies only to modules whose driver IC has built-in RAM. It is not a complete-system latency guarantee.
The 3D function requires a 3D-capable controller. Image rotation in 90-degree steps is supported, while free-angle rotation requires MCTRL R5 and SmartLCT. Confirm these supporting devices and software before designing a rotated or 3D screen.
Maintenance and recovery
Readback of firmware and receiver parameters helps retain maintenance files. Temperature, voltage, bit-error and cable-disconnection monitoring provide information for troubleshooting. Check the existing setup before replacing hardware or changing firmware.
Loop backup depends on primary and backup cable paths between the controller and receiving cards. Configuration parameters can be restored from the factory area, while dual program backup stores two firmware copies. These functions address different recovery needs.

NovaStar MRV412-S questions
Does 24-group RGB support mean 24 module connectors?
No. The specification lists 24 parallel RGB data groups and 12 physical HUB75E connectors. Check both values when planning the module wiring.
Does 18bit+ change the source condition in the loading table?
18bit+ is described as a grayscale-improvement feature. The published maximum-loading figures still specify 8-bit video sources; confirm other source formats separately.
Can I use configuration backup instead of loop wiring?
No. Restoring saved parameters serves a different purpose from providing a backup signal path. Loop backup needs the corresponding primary and backup connections.
