**WORST** ESP board on Amazon DO NOT BUY!
Are you freaking kidding me?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.

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.

Reviewed in the United States on July 20, 2022
On two separate occasions, I’ve ordered a total of 9 modules. One, was defective in that it wouldn’t flash. This is not due to a user issue as I’ve flashed 8 previously and many others before. I threw it away and just ordered another set. So far all is good. Wi-Fi range is not impressive, almost line of ‘site’ but it serves the purpose. On a couple of pieces , the charging ports are loose! Overall, a decent product. However, looking for a different vendor. Hope this helps to the DIY community. Enjoy.
Reviewed in the United States on February 6, 2023
I know these connectors can be fragile, but this is the first board I've ever had that the connector completely ripped off the board on the first insert. I should have read the reviews before ordering. I assumed this was just another ESP32 board.

At least I won't be wasting further time on this board.

Apparently these are seconds or rejects. I purchased two boards. The first had the boot pushbutton smashed and bits and pieces laying in the bag. The second has the micro usb connector lifted off the board. I would recommend spending a few dollars more for a better quality product.

Bought 2. On #1 the micro USB connector snapped off the first time I tried to plug it in. On #2 it took about 10 tries to flash the device successfully. As soon as I tried running it off of a battery the magic smoke came out of one of the chips.

Reviewed in Canada on April 11, 2020
The board did not work and was dead on arrival. It would boot up, show green LED but even after installing the correct firmware to my computer for the USB bridge I could not push code to the device.
