What is ESP8266-12E (ESP8266MOD) input impedance?

I checked input impedance (using multimeter, not actual i guess) at RX pin. It is 450E. What? Just 450? Isn't it supposed to be 1M or something for a MOSFET?
For power input it shows around 300-400E.
An overheats a lot.
Why so? What I am doing wrong?
