After many hours of routing, I came up with this compact, symmetric design using the integrated USB connector. Lufa 20 lufa lightweight usb framework for avrs, formerly known as myusb is my first foray into the world of usb. Soldering really small packages to a board is incredibly difficult, and one of the main reasons is the initial positioning of the IC. The board then shows up as ATmega16U2 under libusb-win32 devices when the bootloader is running.

For windows7 it can be used in hid mode with avrdude command prompt as programming interface. A completely custom LUFA application would use the low-level modules to interact directly with hardware, and a custom driver on the host to communicate with the device.

By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, allowing you to optimize power consumption versus processing speed.
