The AVR Butterfly is a complete demonstration and evaluation kit for the Atmega169 AVR microcontroller with the size of a business card. It includes a 6 times 14 segment LCD glass, a 4Mbit serial DataFlash, joystick, light sensor (LDR), temperature sensor (NTC), a speaker, RS232 Interface with level converter and a button cell to run the board.

The UART, USI, JTAG, In-System programming ines and also Port B and Port D are available on standard 100mil headers.

The firmware of the Atmega169 included in the kit illustrates for example the time, date, your name, the current temperature, voltage measurement and it plays music.

The kit is also an ideal development board which supports all programming modes (serial In-System, JTAG and parallel).
