USB Mini B Client Connector
This connector provides the interface for connection to a USB Host or Hub port.
FTDI FT232R
The FTDI FT232R provides the USB-to-Serial conversion. Operating system device drivers are required in
order to operate with the FT232R to provide the Virtual COM Port serial functionality.
RS232 Level Shifter
The RS232 level shifter converts the signals provided by the FT232R into the voltage levels required by
application RS232 interface.
DB9 PCB Footprint
The DB9 pin-out configured in an industry standard (TIA/EIA-574) pin-out to provide connection to
RS232 peripherals through a standard DB9 footprint . See section 3
