i saw in the kickstarter that the io expenasion board is placed horizontal with the bolt's mainboard this requires larger enclosures, this made me think: why not make the io board vertical? this way only a cm or so is needed in the enclosure width, and no extra height is needed. and when using a removable panel in the enclusre it's easy to access as well. that's what i mean in the upper left, it leaves the grove connectors free as well. i hope this will get through, as it saves time to manufacture holders and extra large enclosures for the io board. (and saving the environment from wasting unneeded resources too) what do you think?
