Thank you for the link. However, the reason I'd like to use an SD card directly (as opposed to a usb expansion) is that I am taking advantage of the 703N's ability to turn off its USB port in order to conserve power. So if I need the extra space but want to turn off all attached USB devices, I can't really use a usb expansion board. Is it theoretically possible to replace the onboard flash chip with a micro sd?

I notice the MK V uses the same chipset as my TP-LINK WR703n. I'd like to tack on an SD card slot to it and am curious as to how I could do this. Would I just wire into the same lines as the flash chip?
