The AT20 is a general small receiving card developed by NovaStar. A single AT20 loads up to 256×256 pixels.
Supporting various functions such as pixel level brightness and chroma calibration, quick adjustment of dark or bright
lines, 3D, individual Gamma adjustment for RGB, and image rotation in 90° increments, the AT20 can greatly improve
the display effect and user experience.
The AT20 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 AT20 has improved electromagnetic compatibility and is suitable to various on-site setups.
