Bevor I flashed this one, I flashed 2 other Kesen KS-601 (1CH)

I have read in this forum, that this Issue is related to a power Issue.

Issue #273 says:
power issue... need to connect to USB vcc instead of 3.3v

So, do I really put the 5V output to the 3,3V from the Switch?
I think this will gonna kill the switch.

Hi,

I decided to test it with 5 Volt on the 3.3V connector.
It works.

Kind regards, Nils
