    Supported by AVR Studio 4. Pre-programmed with a demonstration application, including bootloader No external hardware is required to reprogram the AVR Butterfly The ATmega169 in the kit controls the external peripherals, and can also be used to do voltage readings from 0 to 5 volts. The kit can be reprogrammed a number of different ways including serial programming through the JTAG port.
