A000059, Arduino USB Mini - Development Kit features the Atmega8U2 MCU programmed as a USB-to-Serial Converter

A000059, (USB Mini) Development Kit features the Atmega8U2 MCU programmed as a USB-to-serial converter. This board converts a USB connection into a 5V Serial TX and RX that you can connect straight to the Arduino Mini, Arduino Ethernet or other microcontrollers, allowing them to talk to the computer. It features an Atmega8U2 programmed as a USB-to-serial converter, the same chip found on the Arduino Uno. The 8U2 firmware uses the standard USB COM drivers and no external driver is needed
