Headphone add-on board: SD Card

Hey,

I received and assembled my PSPi yesterday, including the headphone add-on board. It's working perfectly and the sound is so much better than with the built in speakers.

I have one question regarding the SD card slot though: do the primary Raspberry SD card and the headphone board slot share a signal (which is what I assume) or can I have 2 SD cards using this? Unfortunately I didn't look at the traces before assembling it.

Cheers,

Alex

All three microSD slots share the same signal. There is some voodoo that can create one from GPIO pins, but the LCD is using all those.

Right, that makes sense - didn't think about the display. I guess that means getting one huge SD card.

What about the MiniUSB connector? Does it function like a hub in that I can use it in addition to the MicroUSB port on the Raspberry? 

It's probably stupid but somehow I would like to have the ROMs separate from the OS. Whether that's done with a USB stick or SD card doesn't really matter.

Nope. Same deal as the microSD. Everything is just routed straight from the Pi.

There are some very small hubs that could be used. You could remove the two USB pogos and attach a hub in between the Pi and the miniUSB, and add a few extra USBs inside the case.
