Component List
Back Panel
Power Button ⑬
The O6 board includes a dedicated power button for manual power control.
- When the OS is running: Short press the power button to trigger a power event. Depending on the OS settings, this action may display the power menu, initiate a shutdown, or put the system into suspend mode.
- When the OS is powered of: Short press the power button to power on the board.
- Long press (4 seconds): Forces the board to power off.
USB-C Ports ⑫
The dual USB‑C ports on the O6 support USB 3.2 Gen 2 (10Gbps), DP Alt Mode (4K@60Hz), and Power Delivery (PD).
-
A 65W PD power supply(20V / 3.25A) is recommended for powering the O6 from the USB‑C port.
-
Either USB‑C port can power the board. If two power sources are connected simultaneously (e.g., when using two USB‑C monitors with PD capability), the first plugged‑in PD source will supply power to the board.
-
Each USB‑C port can deliver up to 3A to power external USB‑C devices.
Double USB 2.0 ⑪
The double‑layer USB 2.0 host ports provide standard USB support. The combined current limit for the two ports is 1.4A.
Double USB 3.2 ⑩
The dual USB 3.2 host ports on the O6 provide SuperSpeed USB (10Gbps). Each port has a current limit of 1A.
HDMI ⑨
The HDMI Type‑A port on the O6 supports a maximum resolution of 4K@60Hz. Note that HDMI CEC is not supported.
DP ⑧
The DisplayPort (DP) on the O6 supports a maximum resolution of 4K@120Hz and offers 2x MST (Multi‑Stream Transport) capability.
Double 5GbE ⑦
