RS232 with DB9 connector + TTL points on board - USB specification 2.0 compliant with full-speed 12Mbps.
CP2102 Based - Better and Faster than Cheap PL2303 based boards
Supports Windows 8.1 / 8 / 7 / Vista / Server 2003 / XP / 2000 / 98SE / CE 6.0 / CE 5.0, Max OS X / Mac OS 9, Linux 3.x.x / 2.x.x
Create virtual COM port and connect your old devices which use serial port communication

Connect the USB A to B Cable to USB B socket of the module and USB port of the computer, install drivers and you will be assigned a COM port through which you can communicate as you do through a SERIAL port.
You can easily communicate with microcontrollers / microprocessors from your computer through the module. If you need TTL pins for communication, you can find TX, RX and GND points on board, solder 3 berg sticks and connect it to TTL pins of microcontrollers for direct communication without DB9 connector (No need to use MAX232 / MAX3232 for RS232 to TTL conversion in this case)
