⚠️ Important Notes

Certification:This board version is not intended for final product certification. Whole-machine testing and certification are required for end products.

License Responsibility:The purchase price does not include licenses for specific media formats, codecs (e.g., H.265, audio formats), or interface technologies. The buyer is solely responsible for obtaining necessary licenses.

ESD & Handling:This board contains ESD-sensitive components. Proper anti-static handling procedures must be followed during installation and debugging.

Compatibility:Performance of high-speed signals (LVDS, eDP, USB, etc.) can be affected by cable specifications and length. Test thoroughly when changing cables.

System Features:Supports watchdog reset, screen rotation (0°/90°/180°/270°), scheduled operation, multi-language OSD (Simplified Chinese/English), local/USB updates, and auto-navigation (10s/60s timeouts).

Legacy Support:RK3288 was an innovative chip when released. This board supports mainstream audio/video formats and image decoding with 4K H.265 hardware acceleration. Contact support for compatibility details with specific applications.
