The USB to Serial adapter can be used in place of the USB port, you'll be able to use Smoothie fine, but then you miss on all the fun where Smoothie connected to the computer via USB shows as both USB/Serial and Mass Storage, exposing the SD Card.+* At the core you have the LPCXpresso board.

 * The MicroSD breakout contains a SD card ( up to 2GB, that's the size of the cheapest you can find those days anyway ). On the SD Card is the config file to configure smoothie, and you can also put there GCode files and execute them from there. * The MicroSD breakout contains a SD card ( up to 2GB, that's the size of the cheapest you can find those days anyway ).
