1.1 you can get the yourduino mega2560 here. The arduino mega 2560 is a microcontroller board based on the atmega2560 (datasheet). All 3 modes (sdfatsoftspi, sdfatlibspi, sdfat) works fine with uno.

Arduino mega 2560 is a microcontroller board based on atmega2560.

Pins 50 (miso), 51 (mosi), 52 (sck), 53 (ss) support spi communication using the spi library. The spi pins are also broken out on the icsp header, which is physically compatible with the uno, duemilanove and. Due to the many numbers of pins, it is not usually used for common projects but you can find them in much more complex ones like radon detectors, 3d printers. Hi, i am trying to use mega with softwate spi sdfatsoftspi.
