AVR Butterfly is an evaluation tool demonstrating the capabilities of the latest AVR Technology. The tool is shipped with preloaded firmware supporting temperature sensing, light measurement, voltage readings and music playback. AVR Butterfly can also be used as a nametag.
AVR Butterfly can be reprogrammed from AVR Studio using just a serial cable. This allows the tool to be used as a development kit for the onboard ATmega169PV, or even as target hardware for simple applications. The bootloader source code is available as application note.
The code is written for the ATmega169V device, but is compatible and will work correctly without modifications on the onboard ATmega169PV device.
