Hi, I looked over the Gizdino+ schematic: It runs on 5V, so you need level-shifters and you should test the 3v3 pin before with a multimeter to ensure that at least there is 3.3v. Second, the gizdino+-thing has sanguino pinmap, but datasheet says that there is a mapping for arduino-compatibility. Whatever, in the end you must ensure that the hardware spi pins are connected correctly to the card, so mosi to mosi, miso to miso, clk to clk and cs to pin 4 - but i dont know if in arduino or sanguino or gizdino numbering. Even if that is all correct i dont know if it will work because that clone is not very compatible to arduino. better go for the real one - at least take one with the correct cpu. the gizdino-non-plus version may work, but beware - the statement that it is 3.3v seems to be a bad typo to me...
