NovaStar MRV532 LED Receiving Card | 10 HUB320F Ports
$ 17.00
The NovaStar MRV532 LED receiving card uses ten HUB320F connectors and supports RGB real-pixel or dynamic sub-pixel data. Load capacity depends on driver IC and source bit depth; the versioned table below separates those conditions.

NovaStar MRV532 HUB320F LED receiving card
The MRV532 connects LED modules through ten HUB320F interfaces. It supports up to 40 groups of RGB real-pixel data, 40 groups of 3-LED dynamic sub-pixel data, or 30 groups of 4-LED dynamic sub-pixel data. Its calibration and image-adjustment functions address brightness, color and cabinet-to-cabinet consistency.
Check driver IC and bit depth before planning capacity
Specification revision matters: The earlier listing stated 512 × 512 at 60 Hz for 8-bit sources and 512 × 384 at 60 Hz for 10/12-bit sources with PWM driver ICs. NovaStar’s later V1.2.0 specification, dated May 20, 2025, lists the conditions below. The earlier value is not treated as a universal limit for every MRV532 configuration. Confirm the applicable firmware, controller and driver IC for the supplied card.
| Parameter | Specification |
|---|---|
| PWM driver IC, 8-bit source | 512 × 512 @ 60 Hz |
| PWM driver IC, 10/12-bit source | 512 × 256 @ 60 Hz |
| Common driver IC, 8-bit source | 512 × 384 @ 60 Hz |
| Common driver IC, 10/12-bit source | 256 × 256 @ 60 Hz |
MRV532 hardware specifications

Image adjustment and feature requirements
- Pixel-level brightness and chroma calibration using NovaStar’s calibration system.
- Quick adjustment of dark or bright module/cabinet lines, plus multi-batch brightness adjustment.
- Color management, 18bit+, HDR10/HLG and individual RGB gamma adjustment as documented in V1.2.0.
- Rotation in 90° increments; free-angle rotation requires the dedicated MCTRL R5 controller and SmartLCT.
- Low latency of one frame at the receiving-card end only when the module driver IC has built-in RAM.
- 3D output requires a controller that supports 3D.
The earlier page described TU-series mobile-app seam correction. The specification change history records the removal of seam brightness correction in V1.1.0. For this reason, that older app-based workflow is not presented as a universal current feature. Quick dark/bright-line adjustment remains listed in V1.2.0.
Module servicing and diagnostics
Module Flash management supports storage and readback of calibration coefficients and module IDs for modules with flash memory. Smart-module functions and module auto light-up require dedicated firmware. Other documented service features include configuration and firmware readback, temperature/voltage monitoring, Ethernet bit-error detection, stored-image settings and backup functions.
Frequently Asked Questions
How many pixels can an MRV532 receiving card load?
It depends on driver IC and source bit depth. V1.2.0 lists PWM limits of 512 × 512 at 60 Hz for 8-bit and 512 × 256 at 60 Hz for 10/12-bit. For common driver ICs, it lists 512 × 384 and 256 × 256 respectively. Check the version and system configuration.
Which LED module connectors does the MRV532 use?
It uses ten HUB320F connectors. The specification provides separate pin assignments for RGB/three-LED sub-pixel and four-LED sub-pixel data, so match the module wiring to the selected mode.
Does the MRV532 support low latency?
The documented receiving-card latency can be reduced to one frame only with module driver ICs that have built-in RAM. This is a receiving-card-end condition, not a guarantee of whole-system latency.
Can the MRV532 rotate the displayed image?
It supports 0°, 90°, 180° and 270° rotation. V1.2.0 additionally documents arbitrary-angle rotation when used with MCTRL R5 and SmartLCT.
Do smart-module features work with every firmware version?
No. V1.2.0 marks smart-module support and module auto light-up as requiring dedicated firmware. Confirm the firmware and module Flash requirements for the specific cabinet.
