Can someone recommend source for cheap small capacity (32 Mb or more) SD cards? Need it for Arduino project...
but variable quality and shipping time may not be worth the savings.
The small cards keep going up in price. If you ever have any, DO NOT THROW THEM OUT!I am always looking for cards <512MB.
The protocol used on SDHC is different not backwards compatible.

That is a non-optional part of the SD spec. The only thing that differs is the initialization sequence and how blocks are addressed. It would be foolish to implement a design that didn't interrogate the card to ensure the right method was used, so I don't see backwards compatibility suffering any time soon.If I'm wrong, I'd love to hear the opposing viewpoint.
