ATMEGA328P-PU with Arduino Bootloader - Uno
So if you are looking at this product you probably fried your Arduino Uno. Don't feel bad, it happens to the best of us. We have taken the time to put the Uno bootloader on these bad guys, so if you need to replace or upgrade your chip it will be a snap! Of course don't forget you don't actually need an Arduino to use this chip. This is a standard ATMEGA328 AVR compatible chip.
