-if= is a directory of SD Card (from previous command) and of= is a output directory
+from `dd` man page:
+> if=file  Read input from file instead of the standard input.
+> of=file  Write output to file instead of the standard output.  Any regular output file is truncated unless the notrunc conversion value is specified.  If an initial portion of the output file is seeked past (see the oseek operand), the output file is truncated at that point.
