Hi guys,
Thanks for the input..
I've just ordered one of the SDs listed above. - Thanks a lot benne - have seen your project before, great stuff you've done there. I think that was the one that took me to look into SDFat.

Steve, thanks for pulling me on to the right direction. I won't do any changes on the SDcard modules i've here - not that much practice into playing with SMD components, but hopefully with the new module this will get back on track.

Stephen - do you mean i should try the SPI2 or?

it’s pretty easy to remove the SMD resistors , just heating one end with some solder on your iron, normally unsolder both end and they tend to stick to the solder on the iron and easily come away.

There are various ways to modify the board to shirt out the resistors, but this is what I do...

Skin some wire to remove the last 3 cm of insulation.

Split the strands apart, so that one strand is on its own ( you need the other strands to do the other resistors )

Place the single strand over where the resistor was, and use your soldering iron, to apply some solder to the pads of the resistor
note, this needs 3 hands, so you may need someone to hold the strand of wire in place while it’s being soldered.

You should now have you length of wire attached to the board, and you just need to snip off the wire from the board

reading the 103c8 data sheet, if spi1 is remapped on to port B it is all 5v tolerant. seems to me that might be easier.
so if you can investigate afio_remap to make spi1 use port b
try a forum search with afio_remap or just afio ?
it has to written down on the forum as i've read it, something similar with i2c as well.
might be a case of read and adapt

Hi guys!
I've been quiet as i was waiting for the new SD module to arrive - it did today!
So, just got to do a quick test now, with the SdFat lib, and it worked all well!

Connections as follows - using spi1:

Thank you all for the hits, tips and links! :)

(ah, you might notice i got a different MM in use, yes, my second batch came in, they're not the 'baite' ones, as apparently there are clones of clones :D and came pre-loaded with the 17kb RAM 108kb flash.. i'll fix that soon..)
