which pinouts can i use to power the fan…the one own the board is broke !
Not quite understand on this, can you specify more details on this?
And do you have any information of the cooling fan model you used?
Have fun!
cooling fan 3004 for VIN2 heatsink / DIYcase…the SBC connector(for fan) is broken off …so which pins of the 40 pins would work best…pin1 or 5(5v) pin27(3.3v) to grd 5/9… an does the fan work off of Temp.
The 3004 fan can works both 3.3V or 5V voltage, so any power pin with a GND pin on the 40 pins GPIO will work.
But I just wonder why the fan header of your SBC is broken 
Good day!
i broke it …pulling connector out …fan does not work i tried both board and pins nothing …will get another one

Be note that our official ROM control the fan speed is by two GPIO, and the Power PINs on the 40 PINs GPIO don’t with speed control feature.
Have fun!
do you have 1.25 to 2.54 wire converters ??
