I think this uses SPI, so it should be straightforward.

The SD card does use SPI, but I'm going to have to cut some pcb traces and run some wires to the leonardo/zero SPI header.

SERCOM1 can be mapped to do SPI on pins 11,12,13, but it may complicate interfacing with the SD card library (the built-in SD card library doesn't know how to handle multiple SPIs).

I may want to simplify this by running traces; this may be good or not, depending on board population...
