If you click the button on that page labeled: Community Maintained Builds? (it is just above the selectors for all of the builds), then on the github page that link takes you to, click on Download Latest Image?
Or to save you the work you could use the link at the top of the FAQ instructions.
Or just go here: https://github.com/armbian/community/releases (latest build is 211, note they are listed in alpha order so the newest is not at the top)
