ARDUINO UNO
There are two variants to this version of Arduino Uno; the normal version and the surface mount device (SMD) version. The normal version has the integrated chip held by a holder, while the SMD version has an Atmega328controller soldered onto the board. The advantage here is that any damages to in the normal version can be rectified with just a replacement of the chip whereas the whole board has to be replaced in the SMD Arduino.
