How do i can connect arduino PRO mini and supply it with another source? I have an adapter to connect it to usb port, it's right connect VCC and GND to a battery (9v) and the others (BLK, RX1, TX0, GRN) to adapter?
I've tryed but seems it become hot.
it is VERY BAD to connect 9V to the Vcc pin. With luck you did not fry the ATmega chip by using 9V on a device that is designed for an absolute maximum of 6V.
You should read the documentation:
Power
The Arduino Pro Mini can be powered with an FTDI cable or breakout board connected to its six pin header, or with a regulated 3.3V or 5V supply (depending on the model) on the Vcc pin or an unregulated supply on the RAW pin.
The power pins are as follows:
RAW. For supplying a raw (regulated) voltage to the board.
VCC. The regulated 3.3 or 5 volt supply.
The unregulated supply can be 3.35 to 12 V (3.3V model) or 5 to 12 V (5V model).
Oh.. really bad, i've "read Input Voltage 3.35 -12 V (3.3V model) or 5 - 12 V (5V model)" so i tought it can hold 9v.
How i can check that ATmega isn't broken?

Use the USB adapter to hook it up and try to use it. If you can't upload sketches to it, it is probably fried.
