The A4s is a general small receiving card developed by NovaStar. A single A4s loads up to 256×256 pixels. Supporting the pixel level brightness and chroma calibration, individual Gamma adjustment for RGB, and 3D functions, the A4s can greatly improve the display effect and user experience.
The A4s uses high-density connectors for communication to limit the effects of dust and vibration, resulting in high stability. It supports up to 24 groups of parallel RGB data or 64 groups of serial data (expandable to 128 groups of serial data).
Its reserved pins allow for custom functions of users. Thanks to its EMC Class B compliant hardware design, the A4s have improved electromagnetic compatibility and is suitable for various on-site setups.
