I think it has an RBA. I’ve never owned a Smoant Pasito, but as I surf and look around now, they released an RBA “pod head” for both the I and II, and since the II already worked with K-series coils (including the K-RBA) - just as the III works with it now - I guess it might or should be compatible to some extent.
Anyone who wants one, I think they can put it together with the K-RBA (I saw it in stock on SM), but I haven’t looked into it more thoroughly, so I might be mistaken. Below, for example, the compatibility of the Pasito II
