Chapter 6: Precautions for Assembly and Use
Please pay special attention to the following:
- After removing the motherboard from the box, ensure there are no pins or other short circuits caused by shipping before powering on.
- Electronic products are very sensitive to static electricity. Before handling the motherboard, please wear an anti-static wrist strap or anti-static gloves to dissipate static electricity on your body.
- Always plug and unplug components when the power is off. Before connecting the power connector to the motherboard, ensure the power is off to avoid sudden electrical shocks that could damage sensitive components.
- When connecting peripherals via cables, ensure that the pin assignments of the peripherals match the motherboard connectors to avoid short circuits and burns due to incorrect wiring sequences.
- When securing the motherboard with screws, be careful to prevent deformation of the board, which could cause an open circuit on the PCB or components to fall out.
- When connecting a monitor with selectable voltage (LVDS, eDP, etc.), ensure that the voltage selected by the jumper is consistent with the monitor's specifications.
- When connecting peripherals such as SATA/USB/extension ports, pay attention to current limits. When connecting serial and CAN ports, ensure that the serial port voltage levels match. Avoid connecting a UART to RS232 or RS485 voltage levels.
- For RS232, ensure RX-TX interconnection. For RS485/CAN interfaces, ensure A-A/B-B and H-H/L-L.
- When selecting a power supply, ensure that the voltage and current meet the power requirements of the motherboard and peripherals.
- When designing the entire product, consider motherboard heat dissipation and height restrictions.
- When not in use, store the motherboard on an anti-static mat or in a sealed anti-static bag.
