Power Interface
Onboard 12V DC power interface (5525 plug) and 5V / 12V power port provide stable power supply to the motherboard.
- 12V DC Power Interface (Recommended): Supports external 12V DC power input
- 5V / 12V Power Port: Supports powering the motherboard through 12V and GND pins. The 5V pin supports power output only, not input.
Power Button
Mainly used to control the power switch of the motherboard.
- When the motherboard is powered off, press the power button to start the motherboard
- When the motherboard is running, a short press of the power button will trigger a power event, which may display the power menu or put the system into suspend mode, depending on the operating system settings
- Press and hold the power button for 4 seconds to force shutdown
USB Type-C Port
Onboard 1x USB Type-C port supporting DP video output, with maximum transfer speed up to 10Gbps.
USB Type-A Ports
Onboard 3x USB 2.0 Type-A ports and 2x USB 3.2 Type-A ports.
- USB 2.0 Type-A: Maximum transfer rate 480Mbps, all USB 2.0 ports share 1.4A total current
- USB 3.2 Type-A: Maximum transfer rate 10Gbps, each port current limited to 1A
HDMI Port
Onboard HDMI Type-A port, supporting up to 4K@60Hz, does not support HDMI CEC function.
DisplayPort
Onboard DP port, supporting up to 4K@120Hz, with Multi-Stream Transport (MST) support.
2.5G Ethernet Ports
Onboard dual 2.5G RJ45 Ethernet ports, supporting 10/100/1000/2500 Mbps auto-negotiation.
