I need the basics: sine, square, triangle, sawtooth and reverse sawtooth. Arduinos PWMs doesn't perform well at high frequencies unfortunately. Sadly there's little info about what DDS chips in particular those chink generators are based on.

Thanks. Yeah seems standard for chinkshit, doesn't look like an issue for my low demands though. No mention of the bouncing sweeping sadly.

Lel I tried with some of my phones, some do surprisingly well slightly above 20Khz, but beyond that there's just zero output whatsoever.
