Overview
The Uno is a a follow on to the Arduino Duemilanove from ardunio.cc.
The big difference here was the use of a ‘soft’ USB serial interface by programming an ATMega16U2 with as USB serial interface rather than use the FTDI chip. This also allows a custom programming interface potentially although I have not yet seen one emerge.
When released, the Uno became the “reference” Arduino and its release coincided with the release of the 1.0 version of the software.
