The strength of the UNO with quarter the size!

The miniUNO is an exact replica of the UNO. Where the main difference between them is the fact that the miniUNO's size is 1.35" x 1.05", while the UNO's is 2.7" x 2.1". And like the UNO, the miniUNO is based on the ATmega328P microcontroller, and is compatible with Arduino IDE and ready to plug and play. It sports 14 digital I/O pins (6 of which can be used as PWM outputs), 6 analog input, the ever so popular micro USB, and a power jack.
