The Uno has changed that by exchanging the FT232RL chip with an atmega8u2 chip. Finally, there's an extra 3.3V regulator (LP2985) for a better 3.3V supply. The FTDI chip has also been replaced with a atmega8u2 which allows for different kinds of USB interfaces. So even though the chip is the same, you get another 1.5K of extra flash space that was previously used by the bootloader. It has a smaller bootloader called OptiBoot (more space for users' projects) that runs at 115K.

In 2010, we have the Uno! The Uno still uses the 328P chip and the power switcher.

The bootloader takes up 2KB of space and runs at 57600 baud. This makes it easier and faster to move from programming to standalone and got rid of some confusion. Yet another doubling of space and memory! Another upgrade is now the power is automagically switched between USB and DC-jack which removed the previous jumper. This one also upgraded the chip again, to the Atmega328. Auto-resetting was also added which makes life awesomer for everyone. The bootloader takes up 2KB of space and runs at 19200 baud. The Diecimila also added two extra header pins for 3.3V (from the FTDI chip) and the reset pin which can be handy when a shield is covering up the Reset button. The great thing here is double the space and memory (16K instead of 8K). The Diecimila updated the chip from the Atmega8 to the Atmega168. The first popularly manufactured Arduino was called the NG (New Generation, like Star Trek, yknow?) The NG used the Atmega8 chip running at 16 MHz and an FT232 chip for the USB interface. Arduino TimelineBut first…some history! First there was the serial Arduino (what's the name of it?) with RS232 which was not used outside of the Arduino team & friends.
