Difference between two Arduino Uno's

Development Tools IDE 1.x

Hello everyone. I have recently bought two different Arduino Uno's (see picture in attachment). They look a little bit different but I am not sure what the actual difference is. I have tested a program on both of them and I get the same results. Is there a difference? Is one faster/better than the other?

Thanks a lot!

Left hand looks like a clone ripoff - the chip next to the USB connector is not an FT232 nor a 16U2, so that says to me that someone is ripping off the Uno name.

The right hand unit looks like an Uno R3 with 16U2 USB interface.

If both are bootloaded as Uno, both have the same '328P die inside the package, and both will function the same.

Thanks for answering. I expected it was a copy, because it was very cheap. But as I understand it will not matter which one I use?

It will not matter as long as you not attempting to do HID stuff, which requires reprogramming of the 16U2.

The SMD part alsosomewhat higher current handling capacity (300mA) as it as two VCC pins vs just 1 on the DIP (200mA).
