[OpenTRV-dev] EU radio band 48

[Bo Herrmannsen]

@Joseph Heenan

The radio modules are sub-assemblies... they come in the form of a little
board where the edge has half via's

*on the board it is fitted on you have a pattern that matches up and you
simply put it on the board and solder it in place*
