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 Section 3.1 Evaluation Board Overview).

Depending on the setting of Power Mode (Normally On / Normally Off) switch, the board will boot as soon as

it receives power.

The control buttons (see Fig. 3.1 The baseboard with RINGNECK SOM-PX30-uQ7 module) 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 uQ7 module.

Several slider switches are located on the lower left:

• LID SW is routed to a GPIO on the module, simulates lid open/close.

• Power Mode (Normally On / Normally Off), as described above, sets the state after power loss.

• BOOT SW (BIOS Disable / Normal Boot) forces SD card boot or the normal boot order, respectively.

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.
