It is challenging to build a company on a single product- especially one that has a low ASP.
That said, in order to acquire the capital that will be needed, you'll probably need to do a couple (or more) rounds. If you attempt to raise it all now- it will be harder and will take a big chunk of the equity.
The quicker you get some kind of "traction"- the better.
