... or do I need to remove power from the board before inserting the MicroSD card?
Is the MicroSD connector hot-pluggable?
The micro-SD is hot-pluggable. I do it quite a bit. But I'm checking with Scott to see if it's officially supported by the hardware and will get back to you.
Usage hint: The refresh button at the top of the file pane will update the content list after a swap.
Confirmed: The micro-SD slot is officially hot-pluggable.
Thanks, Patrick, for the fast response
