There's another piece of text at the bottom of the main page:

Module Licence
--------------
It is completely free for personal use. If you like this module and you 
are interested to use it for commercial use, please contact us. There is 
a pretty high chance, that we will agree on a free license for your 
commercial project or a small fee $7 may apply.

First of all, we are not developing a commercial product. We are not 
going to manufacture and then sell hardware. We will certainly contact 
those guys, if we eventually decide to reuse their module, and ask for 
permission. Right now we just need to understand, whether this module 
can get us closer to Alpha or not.
