Attaching the integrated USB and Power cable is a straightforward process and Crystalfontz has integrated a USB bridge board over the original serial interface. Towards the bottom of the 632 PCB is a mini 4-pin header that is labeled Ground, Data Positive, Data Negative and +5 volts. All that is required is to connect one end of the bundled USB and data cable to the 4-pin header of the USB interface.
