can you order a versalino without headers or even better with them straight up
Of course. These versions are available in the original Versalino Uno, and the current Versalino Nano. The new Versalino Uno 1.3 has already been manufactured in the standard configuration, but once they run out they will be available as fully loaded and self assemble kits which will allow for any number of personal configurations.
