I'm looking at the RRD and Geetech fan extenders, and it looks like they might be wired opposite of each other. Has anyone else seen this?

The RRD fan extender (http://www.makerfarm.com/index.php/r...-extender.html) looks like it has the fans on D4/D5, and the Geetech one (http://www.geeetech.com/wiki/index.p...D_Fan_Extender) looks like they're on D6/D11.

The actual Geetech page referrs to their extender as an "RRD" fan exdender, and the top of the page references pin 4, just like the RRD extender, but the photos clearly show it wired to D6/D11 and the bullet down further in the page says to define FAN_PIN as 6.

For the record, when I recommend soldering pins to the top, for a servo, this will only work with the real RRD extender that has D11 free.
