## Description

Plugs into a USB port on your computer and provides you with a hardware serial interface: perfect for giving your home-brew Arduino-compatible projects a USB interface compatible with the Arduino IDE.

Provides a 6-way female connector with pinout matching the popular FTDI cable. Just plug it into a header intended for an FTDI connection, and you're good to go.

But this board is so much more than just a USB to serial adapter: it's actually a really useful general purpose breakout for the ATmega16u2 MCU! We've included headers along the edge of the PCB for the rest of the I/O pins, so you can re-flash the board with whatever firmware you like and use it as a general purpose 16u2 development board.
