Hi,
I plan to use the CFA835-TFK (USB-powered) LCD modules with a CFA-FBSCAB for fan control and temperature measurements. I only have a dedicated 12V power supply in my system. The question is if I can provide 5V from the LCD to the FBSCAB (logic), and only connect the external 12V supply for the fan power. And, if there are any jumpers on the CFA-FBSCAB to make this happen.
Specifically, the CFA835-TFK manual says:
"Power steering jumpers on the FBSCAB module, configure it to be supplied with 5V power from attached CFA835 module, or by a PC “floppy-disk” style 5V/12V connector. See the FBSCAB datasheet for more."
But I cannot find anything about this in the FBSCAB datasheet.
