The title pretty well sums it up, if I wanted to choose which side of an expansion module faced up, maybe to choose which direction a right angle connector went, could I flip the module over? If not this seems like a pretty useful feature to me.
Step 4 of the quick start guide says the text and logo must be facing down, so the ones they have are currently not reversible.
Nope, they have rails and a clip type mechanism to hold them in place. From the photos I’ve seen, these are directional.
