A7s Plus Receiving Card: Capacity and Display Functions
The NovaStar A7s Plus provides a compact hub-board interface for LED cabinets, with up to 32 parallel RGB data groups or 64 serial data groups, expandable to 128. Its maximum pixel load depends on the module’s driver IC.
The reference values below follow NovaStar specifications V1.2.5, dated May 15, 2025. The legacy download URL at the end of this page is retained, but returned a page-not-found response when checked.

Color Calibration and Screen Uniformity
A7s Plus supports color management, 18bit+ and pixel-level brightness and chroma calibration with NovaStar’s calibration system. Dark or bright seam adjustment addresses visible differences at module or cabinet joins. The V1.2.5 reference also includes multi-batch adjustment to reduce brightness differences between production batches.
Individual RGB Gamma adjustment works with NovaLCT and a controller that supports the function. 3D output likewise requires a 3D-capable controller. Supported image orientations are 0°, 90°, 180° and 270°.
Maintenance and Backup Functions
Smart-module operation requires dedicated firmware. Automatic module calibration and module Flash management require modules with flash memory. Mapping identifies controller, Ethernet-port and receiving-card positions, while temperature, voltage and communication monitoring support service work.
Dual-card backup uses two receiving cards on a suitable hub board; NovaLCT V5.2.0 or later supports monitoring their working status. Loop backup, dual configuration storage and dual program backup provide additional recovery functions. Match the card revision, module and firmware before using features described in a later specification.
Frequently Asked Questions
What is the maximum A7s Plus pixel load?
The V1.2.5 reference specifies 512 × 512 at 60 Hz for PWM driver ICs and 512 × 384 at 60 Hz for common driver ICs.
Does A7s Plus support brightness and chroma calibration?
Yes. It works with NovaStar’s calibration system for pixel-level brightness and chroma calibration, and supports color management and seam adjustment.
Can A7s Plus display 3D content?
Yes, when used with a controller that supports 3D. The receiving card alone does not provide the complete 3D signal chain.
What is required for automatic calibration after a module replacement?
The replacement module must contain flash memory with calibration coefficients. The card can upload those coefficients when powered on.
Is the original A7s Plus PDF link still available?
The legacy link is retained below, but it returned a page-not-found response when checked. The parameter table identifies the separate manufacturer document version used for verification.
