Ratings and reviews

The ads are quite invasive. A fullscreen video that can only be skipped after waiting for several seconds watching it. I guess the functionality works, I didn't check til the end.

Works as expected serially connecting my android phone to my itsybitsy M0 Express. Nice to have memories as well! Thanks!
