I also miss-read that as GPIO15 shorted to 0V, thanks for pointing that out, my befuddled brain was mistakenly assuming the lettering applied to the adjacent pads on the module, as well as the pins going to the outside world. It is obvious from the pictures below, this is not the case and makes perfect sense.

I fell for that to - sorry for any bad infomation as a result.
Looks like your on top of things now.

FYI, I recently bought a few of these white boards from this aliexpress vendor:

Had a little trouble with the first one. Couldn't power up the esp-07 i attached.

Turns out all three resistors are 10k -- and the center one should be a jumper since the regulator position on the back side is empty.

I am trying to flash an esp-12 connected to this board using USB serial (CH340G) adapter with the Arduino IDE.

My connections are


However, it would seem that the IDE is unable to put the board into bootloader mode, as Arduino throws up a


EDIT:
Nevermind, I need the proper pullup resistors on GPOO and RST.

After breaking my first esp12 (5V to ground...) i bought 2 ESP-12E. My first one had one of these boards, and i just wired it up and it worked, now the new ones dont work unless I short the hole next to the VCC with 3.3v, using the same wiring has the first one i got.

Any ideas why this happens?
