This board is not supported by the stock Arduino IDE, but can be easily added: Ebay does not allow us to provide a link to the instructions, but they can easily be found by searching for "pro micro Arduino IDE"
Once this is installed, you should select Board : "Sparkfun Pro Micro", and Processor : ATmega32U4 (3.3V, 8Mhz). If you accidentally program this as a 5V/16Mhz board, you will lose access to the USB port, this is recoverable, but can be tricky.
Thanks for your interest!
