3.2 Power Supply
The baseboard can operate with a single 12V DC power supply.
Power can be controlled manually from the board using the Power control buttons and switches, located on the
lower right side of the board (see Evaluation Board Overview).
Depending on the setting of Normally On / Normally Off switch the board will boot as soon as it receives
power.
3.3 Control Buttons and Switches
The control buttons provide the following functionality:
• Power toggles the module power supply
• Reset triggers a module reset
• Batlow, Sleep and Wake are routed to GPIOs on the Q7 module
Several slide switches are located on the lower left:
• LID is routed to a GPIO on the module, simulates lid open/close.
• Normally On / Normally Off, as described above, sets the state after power loss.
• BIOS Disable / Normal Boot forces SD card boot or the normal boot order, respectively.
3.4 CPU Fan
Operation in high environmental temperatures may require a CPU fan. The fan connector is located next to the
bottom right corner of the Q7 expansion area (see board overview).
