Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.

ConfigurabilityReplaceable chip

The ATmega328P can easily be replaced, as it is not soldered to the board.

MicrocontrollerEEPROM

The ATmega328P also features 1kb of EEPROM, a memory which is not erased when powered off.

DocumentationPowerBattery Connector

The Arduino UNO features a barrel plug connector, that works great with a standard 9V battery.
