A bootloader comes preinstalled which allows programming of the chip over USB without an external programmer. Updated January 28, This does not seem to have any effect. The DFU Bootloader also requires a driver. If you need to protect your code from being read but lack an external programmer to set the lockbits, choose the Atmel bootloader. The key simply connects to the USB port of a personal computer to retrieve on-board documentation and run AVR programs. Note that this could also be setup to run automatically at boot, thus allowing for some autonomous operation:
