SD Card thought

[AtomSoft]

Should be the same. I think Sandisk is the standard or something really...

The standards for SD cards are a little fuzzy, but mainly on the high speed high capacity ones, I think the SPI access ability is optional but very common.

Yeah the main difference between SD Cards and Micro cards are the size... i think...

Now there are different types also like SD, SDHC, SDXC etc...

Now they are the same for micro i assume.. SD Micro, SDMicroHC.... etc...

I have read a micro SD usinf normal SD code.. so i say they are the same....

Coming Soon!!!

SPI mode on SD cards is not optional. It's optional on MicroSD devices. The SD Association sets the standards for SD Cards, Sandisk is one of the founding members.

Even though SPI is optional on MicroSD devices I haven't found one that does not have it. I have heard of them, but I couldn't name manufacturers or specific models.

thanks for clearing that up... just so much to read to get info like that

This doesn't relate all that much, but I saw this tear down of SD cards and fakes. It was really interesting and has some insights into the industry:

Those are nice boards on your blog Jason. That clear PCB material is pretty cool.

Yeah nice and thin and light... From DipMicro heh .. its the .009" board

micro sd:

they may be 1.8v devices, i'm not sure so check that datasheet.

Anyways, I took a quick look, it is the same voltage for micro sd, 3.3v

Thanks for the fill in Dirtylude, I wasn't quiet sure and I'm too busy to look it up. Nice to know.
