，

install FTDI drive. Usually it will

install automatically. If not you need to install manually.

download the FTDI driver

here

3. If there is nothing wrong with the hardware of board, you can find COM port in

device manager. But every computer has different COM watchword, you need check

by yourself.

4. Unzip the firmware, drag all the files into Arduino IDE.

（

I use Arduino1.0.5)
