This is yet another good AVR development board which is actually cool, as you can use it for many purposes like testing your applications or simply develop a end application as it includes many built in peripherals like four LED’s, four  buttons, piezo speaker, potentiometer connected to ADC(including filtered analog voltage and adjustable AREF). Board also is featured with two temperature sensors where on gives analog value while another outputs temperature in PWM forms.

Development board also has connectivity to standard RS232 interface and built in ISP circuit. - You don’t need additional ISP cables -only COM cable in order to program ATmega. Board files are downloadable here.
