Of course the uploads are longer, but it did the job for me : i did not have any upload error since

I also installed the latest CP210x Windows driver (v10.1.1 for Windows 10) but i don't think this is necessary

But this is not sold seperatly at all.

By adding a capacitor, I was also able to solve the issue. But for me this looks more like a weak reset circuit in the M5Stack board rather than a drive issue. At leat adding the capacitor is is more a workaround rather than a solution.

Ripple on the RST pin causing resets whilst communicating. I used a 10uF successfully after trying all available CP210X drivers without success.
