== Using 12V fans when VIN is 24V ==
 
If you need to use 12V fans buy tou VIN is 12V, if all your fans are 12V then on the Duet Wifi and Duet Ethernet you can do this:
 
* Remove the V_FAN jumper
* Connect the two input wires of a 24V to 12V common-negative step-down converter to an always-on fan output, taking care to get the polarity right
* Connect the +12V output of the converter to the centre pin of the V_FAN jumper block.
 
== Using a fan connector as a general purpose output ==
