The Arduino Uno SMD is a version of the Arduino Uno, but uses a surface mount version of the Atmega328P instead of the through-hole version. This version was made in response to a shortage in supply of the through-hole Atmega328P. The board is based on the ATmega328 ).It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, 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.
Main changes from the Arduino Uno R3 DIP
1. Two rows of the holes for the pins (Male and Female). So it can be connected with normal Female Jumpers.
2. Additional 3 rows of the holes for wiring.
3. Changes to the DIP package of ATMEGA328P to flat package.
