This board converts a USB connection into 5 volt TX and RX that you can connect straight to the Arduino Mini or other microcontrollers, allowing them to talk to the computer.

It features the ATmega8U2 programmed as a USB-to-serial converter, the same chip found on the Arduino Uno. The USB Serial module has an ISCP interface, allowing you to reprogram the chip when placed in DFU mode.

The pinouts on the connector are compatible with a standard FTDI header.
