The AzarPixel A4s receiving card is designed for professional LED display systems, combining a compact design with reliable performance. Each card supports resolutions up to 256 × 256 pixels and handles up to 24 groups of parallel RGB data or 64 groups of serial data, with support for up to 128 groups through a firmware update. These capabilities provide stable data transmission for a wide range of LED display applications.
NovaStar solutions support accurate color reproduction and consistent image quality. The A4s also provides gamma adjustment for optimized grayscale performance and white balance in low-brightness conditions.
Built for demanding operating environments, the A4s features high-density board-to-board connectors for improved durability and resistance to dust and vibration. The card is RoHS approved and operates across a temperature range of -20°C to +70°C, making it suitable for both indoor and outdoor LED display systems. It also supports 90° image rotation, 3D functionality, and rapid correction of dark or bright lines at panel junctions.
The A4s simplifies system maintenance and troubleshooting with features including smart module support for storing calibration coefficient data and detecting module errors, module Flash management, mapping, real-time temperature and voltage monitoring, loop backup, dual power supply status detection, and support for cabinet LCDs. Firmware setup and reading functions further simplify system configuration and diagnostics. The NovaStar A4s is suitable for demanding LED display installations, including public displays, store signs, and other commercial LED systems.
