hardware hack Le Potato max power draw on GPIO pins?

[V10lator]

I know the RPi is pretty limited on the GPIO pins. Now my question is how it looks on Le Potato, i.E. is it possible to power a fan directly from the GPIO pins? Powering it from the 3.3 V line seems to work just fine but I fear damaging hardware by trying to connect it to a GPIO instead.

The GPIO pins are very low current, 3-5 mA if I remember correctly. I don't think you'll damage the SoC, but it certainly won't drive a fan if my memory is correct.

A simple MOSFET, such AO3402, should do the job ...
