I have esp12F that programmed with USB-TTL from arduino IDE
The wires setup during program is running
While on GPIOs of ESP12F
When i touch the ESP12F, i feel my thumb so warm and the feel like little near iron temperature. I dont have termometer. So i just tell what i feel, what im afraid is that hot state is indicating short circuit but i'm sure there's no short at there. If short, the blink program wouldn't blinked, the fact it's blinking. I'm not using any resistor for it, i'm just directing connect using cable jumper.
Or should i think that hot is a normal? Due to current that stuff needs?
Also im wonder are GPIOs on ESP12F is 5V tollerant? I have read many article, they are have different question that make me confused.
