The JeVois software is GPLv3, so your software using it would have to be GPLv3 too and you have to provide your source code. Note that it is not LGPL. When you write a module, a lot of the core JeVois code gets compiled into your module, because it is template code. So your module incorporates a big chunk of JeVois code and hence must be open source under GPLv3. If that is a problem, please contact us by email and we can discuss different licensing terms. Closed-source licenses are possible on request.
JeVois (R) is a registered trademark of JeVois Inc, a California C-Corporation. So that limits your use of the name.
Usually, the best is to contact us to negotiate an OEM deal, i.e., we can provide a custom version of our hardware and/or software with a closed-source license and your own brand name on the hardware. The main thing here is volume; if you are planning on 100 units then the costs of making a new version will likely be too high to be offset by your profits. But if you have a market for 10,000 units or more, then let's talk, anything is possible.
