It isn't possible with M3Simply yet.
The next FW update might add SDHC support for the M3Simply/R4.

Right now i do not have any information regarding when the M3 Simply wil support SDHC. But as soon as I get some new info ill be sure to post it here.Any ETA for the firmware that will allow SDHC on the simply, g6team? Also, how is that going to work? Is the PCB flashable?
