What wasn't wrong with this dev board?
The mounting holes are drilled off center, and you can see in image 2 that this is entirely unsound, structurally, and would be a real pain for anyone that was going to mount their devoted to a project.
But I was not upset because I was not mounting that way.
Next, the EN button, which is waaaaaaaay on the other side of the board all by its lonesome in the middle of nowhere and for no reason, seriously just dropped right off the board the first time I took it out of the ziplock baggie packaging that i have only ever seen in shops where hippies buy their "deodorant", which should be the first red flag when you purchase one of these types of dev boards.
By I was in not coding to use the button, so I was unabated.
But then....
Then they came for my USB port.
I pligged in my cable and the whole port just slid off of the board like there was never any flux on the pads or leads.... Probably because there WASNT any flux on the pads or the leads. To Avd for this much money you can go buy a half dozen 18650 battery clips and a halfway decent ESP32 dev board to wire them up to. It should take all of 5 minutes and will be or way better quality that if you buy from these ripoff artists.

At least I won't be wasting further time on this board.
No doc on much on any thing
Will not run while charging.
Causes USB rest if Bat in place connected to PC
All in all not good for beginner.
Great concept poor execution.
