A7S Compact LED Receiving Card
The NovaStar A7S (A7s in the specification) is a compact receiving card for synchronous LED display systems. It connects to LED modules through a compatible HUB board and supports up to 32 parallel data groups, with extension to 128 serial data groups. The small 70 × 45 mm footprint suits cabinets where board space is limited.

Calibration, Rotation and Firmware Requirements
A7S works with NovaLCT and NovaCLB for pixel-level brightness and chroma calibration. Quick seam correction adjusts dark or bright lines between modules and cabinets. Individual RGB gamma adjustment requires a supporting controller and NovaLCT V5.2.0 or later.
Image rotation is available in 90° steps, but the V2.0.0 specification states that calibration is not supported after rotation. LVDS transmission and smart-module support require dedicated firmware. For 3D operation, use a controller that supports the 3D function.
Module Maintenance and Redundancy
With module Flash, the receiving card can read a replacement module’s ID and calibration coefficients at power-on. Mapping shows cabinet and Ethernet-port information to help identify the wiring route. Stored images can be configured for startup or loss of cable connection/video input.
Voltage and temperature can be monitored in NovaLCT. The general 5-pin LCD module connects through the HUB board; LCD backlight control, run-time reset and bit-error detection are supported with NovaLCT V5.2.0 or later.
For dual-card backup, a suitable HUB board can carry two A7S cards so the standby card takes over if the primary card fails. Dual-power backup detection and loop backup are also supported. Configuration files, firmware and calibration coefficients have readback or backup functions described in the PDF.

Frequently Asked Questions
What is the maximum load of a NovaStar A7S card?
The V2.0.0 specification lists 512 × 256 pixels with PWM driver ICs and 384 × 256 pixels with common driver ICs. Select the configuration for the actual module and driver IC.
Does A7S connect directly to HUB75 module ribbon cables?
The A7S uses high-density connectors and connects to the display through a compatible HUB board. Confirm the HUB design, connector and pin definitions for the cabinet before replacement.
Can I rotate the image and retain calibration?
The image can rotate in multiples of 90°, but this specification states that calibration is not supported after rotation. Account for that limitation when planning a rotated cabinet layout.
Do LVDS and smart-module features require special firmware?
Yes. Both features are listed as requiring dedicated firmware. Smart-module operation also depends on the corresponding module hardware.
How does A7S dual-card backup work?
A suitable HUB board carries two A7S receiving cards. If the primary card fails, the standby card takes over. NovaLCT V5.2.0 or later supports monitoring the working status of both cards during dual-card backup.
