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.

| LED | Status | Description |

| Orange | Solid | Link established (device connected to network) |
| Green | Blinking | Data transmission in progress (network activity) |
| Off | - | No link detected (cable unplugged or network issue) |
Fan Interface
Onboard standard ATX 4-Pin fan header, supporting PWM control and tachometer.
Note: The motherboard has silk-screen labels for easy identification and connection.

| Pin | Name | Description | Pin | Name | Description | Pin | Name | Description |
|---|---|---|---|---|---|---|---|---|
| 1 | GND | Ground connection | 2 | VCC12V | Power (12V) | 3 | TACH | Tachometer signal (fan speed feedback) |
| 4 | PWM | PWM control signal (3.3V) |
40-Pin GPIO Header
Onboard 40-Pin GPIO (General Purpose Input/Output) interface, providing highly flexible interface support for hardware expansion.
Users can connect various sensors, actuators, communication modules, displays, and other embedded peripherals through the 40-Pin GPIO interface, enabling rapid prototyping and functional verification in fields such as IoT, robotics control, and industrial automation.
