Can someone please look at my PCB – it’s my first one, and the circuit is pretty simple.

However, when I soldered the components in and programmed the ESP8266, for some reason all the pins of the ESP8266 go high as soon as I power on the circuit and the ESP heats up immediately.

I picked up another board and ESP-12F module and installed just the ESP-12F, and the pull-up/pull-down resistors. Same result. Not sure what I did wrong, but would be great is someone can have a quick look.
