Transformation to SM card camera XD card method

Some are still using the old camera SM card, SM card while the high prices to many of my friends just for a card and had to give up the camera, but some cameras use SM card is very good, definitely not now that the imaging a little more than ten million pixel digital comparable. In order to save these old cameras use SM cards are abandoned to their fate, let us work together to transform.

Specific principles that SM card and XD, are the memory card itself does not control circuit, pure chip architecture, we can use the camera's SM card reader circuit transformation to read XD cards, but still can not change the maximum capacity can only be read 128M restrictions. Only 128M of XD card is very easy to get, the price is very cheap, and unlike SM card XD card as easily damaged.

The program follows in particular, XD cards and SM card, are without a reader circuit storage solutions, SM card, SM card reader circuit and essentially the same, while the SM card maximum support to 128M, so it provides us with XD card instead SM card approach. XD card instead of using the SM card is as simple as a card reader or a few welding line only, the rest is up to your ability!

SM card XD card instead of using the principle is very simple, SM card reader and XD cards are no pure memory chip control circuit, just XD card production process advanced than the SM card only, two basic control circuit are the same, just those who use the old SM card reader circuit inside the camera body can only read about 128M, therefore, the transformation of a good circuit can only use the maximum of 128M XD card (in fact, some of the old camera supports XD cards only support a maximum of 128M XD card is for this reason).
