Excuse my ignorance, but would this board interface with the GPIO pins on a banana pi 1 and work? I see a DC-in on the board, is that just to power the USB and SATA? I understand the banana pi should not receive power input over GPIO.
Could a 5V power supply and separate 12V power supply be wired directly to molex-SATA then be used to power a 3.5" drive? I am not sure myself. Seems weird to have two plugs in the wall to power a drive or two... but would that configuration work assuming you wired the molex's four connections correctly? I have a half dozen UL listed 12v laying around and lots of USB chargers, im betting lots of people do as well. If this worked it would be a pretty cheap solution. Cheers!
