If the boards are powered with less than 7V, this may lead to the 5V pin providing less than intended, thus making the power source and the board unstable. The boards’ input voltage range is from 6V to 20V. Both Arduino boards require the power jack of the adapter to be a 2.1mm center positive plug, while the wire leads from a battery holder can be inserted into the GND (Ground) and Vin (Input Voltage) pin headers in the POWER connector. The use of an external power supply can be done with the use of batteries or an AC-to-DC adapter. With the power source being automatically selected either way, both can be supplied with an external power supply or using an USB connection. ![]() In terms of power, both the Arduino Uno R3 and the Arduino Uno SMD have the same specifications. This makes it cheaper, but this version does not enable the user to remove or replace the microcontroller, unless with the use of specialized tools (e.g., hot air gun). On the other hand, the Arduino Uno SMD makes use of an SMD or Surface-Mount Device. The Arduino Uno R3 makes use of the DIP or Dual-in-line Packaging and an IC socket, provides a great way to remove or replace the microcontroller if it becomes damaged or broken beyond repair. In observing the pictures of the two Arduino boards, the most obvious difference would be the packaging of their ATmega328p microcontrollers.

However, there are two types of Arduino Uno boards that people still struggle to know the difference, which are the Arduino Uno R3 and the Arduino Uno R3 SMD. Many beginners (and even amateurs) who plan to create projects using Arduino® Programming and Electronics would most likely choose the Arduino Uno. ![]()
