⚠️ Important Notes & Precautions

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

USB Device Compatibility & Power:

USB 2.0 port supplies 5V/500mA. Devices requiring higher current (e.g., some cameras need 5V/2A) may not be recognized.
USB portable hard drives with high inrush current (>500mA) may cause board issues; use a USB 3.0 port if available.
Confirm power requirements of your USB devices before connection.

ESD & Handling: This board contains ESD-sensitive components. Use proper anti-static procedures during handling, installation, and debugging.

Signal Integrity: Performance of high-speed signals (LVDS) is influenced by cable specifications and length. Test thoroughly when changing connection cables.

Panel Power:

For 3.3V panels with inrush current ≥ 1000mA or normal current ≥ 600mA, contact our engineers for component verification.
5V panel normal operating current should be ≤ 1500mA.

General Precautions:

Do not apply excessive force, twist, or disassemble the board.
Ensure all cables are correctly connected before powering on. Do not plug/unplug cables while the board is powered.
Keep the board clean and dry. Use a soft, dry cloth for cleaning.
For external I2C or USB devices, or custom keypads/panels, consult our technical personnel for compatibility and cable requirements.
