SD card for Atheros 9331 chipset


Recommended Posts

Good luck, wiring directly into the micro controller is not easy and not for the faint hearted.

Though both devices are running openwrt the kernels are set up differently, so I would advise against using the pineapples firmware files. Use Spazi's link above for the expansion board that adds a useful USB bus.

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 have to say, I have no idea if it's possible since I'm not a electronics builder/geek. I guess everything is possible.

How about upgrading the onboard flash?


the guy who made the mod also sell them modded on ebay:


I did a read up, and I'm guessing that if you manage to mount a SD-card you have to change the firmware too. Just guessing.
