I have a Genuino board. Do I need to do anything special to make it work with Afero?

No, since Genuino is basically the same board as Uno offered in countries outside the U.S., your board works with Afero the same way as any Uno board. You can use the Afero Plinto Arduino® shield [hotlink to Plinto page] to make it easier to connect Modulo to your Genuino board.
