I have one of those WAVGAT Uno r3 clones, and when I first got it I read all of the issues people have with them trying to upload sketches, and thought to myself.. Ahh for 4 bucks, I can deal with an extra driver install.. man, was I wrong..
After like an hour of trial and error when I first got this thing I was finally able to upload a sketch to it.
Now, today.. several weeks later.. I just wanted to update the code.. should be simple right? NOPE.
Back to square one. I've tried, reinstalling these CH340 drivers a dozen times, the IDE itself, different USB ports, different cables, different computers, different programmers, double and triple checked the COM ports.. still can't.. times out after 10 tries.
