Hi!
On the Orion O6’s PCIe x16 slot (which has 8 lanes of PCIe v4):
-
Does the PCIe slot have 12V power supply both when the SBC is powered by ATX, and by USB-C PD?
-
The documentation https://docs.radxa.com/en/orion/o6/hardware-design/hardware-interface#pcie-x16-slot- says when the SBC is powered " With USB－C PD power: Maximum power from the PCIe slot is 15W". Curious, if you power the SBC with USB-C PD and the PCI slot draws constantly 25W or 20W, what actually happens - will you over-burden some 12V voltage stepper and risk permanent damage, or should it supposedly be OK?
For clarity: To my best awareness, the specific PCI card I want to connect which draws 20-25 watts, mostly only draws 12V. I.e. it draws almost no 3.3V.
From the O6’s PCB design, does it look OK to draw 20-25 watts of 12V on the PCI socket when the O6 is powered via USB-C?
Thanks
