I ordered 4 modules and three of them failed to flash automatically and I had to boot into bootloader manually. All four of them had brownout (low voltage) when I uploaded a sketch with WiFi. These are not proper Devkit modules and are made by some cheap manufacturer. The solder is not reflowed correctly so many joints are poor and some of them not even conductive. I tried to fix some but the alignment of the modules are off so it's hard to fix the joints without bridging them. I didn't expect this kind of poor quality from banggood.
