The ATMega328 board is a microcontroller board based on the ATmega328, The board contains everything needed to support the microcontroller. The board need 5VDC to power it. Simply connect the power connector to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. You can program it with the ICSP connection. The ATMega microcontroller boards can be programmed with a serial port programmer, parallel port programmer or USB port programmer.
