[sdiy] Audio Weaver for ST Discovery boards -Free!

Thu May 11 17:11:09 CEST 2017

OK, The ST product is royalty free on the devices sold on the ST discovery boards.

If you use the same type of chip on your board and you are not obligated to pay us any royalties. If you wish support or more advanced tools then that is a License and royalty scenario.

It is a killer deal to get the tool for these parts for Free. No royalties and you can distribute your code the same way.

More advanced tools are available and you can see the differences on our website.
