I assume the author is from the US (as they speak about the FCC). I had a 30 second look at these dev boards and their instructions. There is no FCC conformity declarations or markings, so US customers can't use it.
Just order it off Aliexpress.
It's fine to have a really expensive compliance regime, so long as you understand how that drives the small end of the business offshore.
Then it's on you as the importer. This is part of why lots of stuff on AliExpress and dodgy Amazon 3rd party supplies is cheap. It's non compliant stuff that is not even sold in China. It's export only, and for the wrong reasons.
