Arduino Uno SMD
The Arduino Uno SMD is a compact variant of the Arduino Uno development board, using surface-mount components. Based on the ATmega328P microcontroller, it offers the same functionality and compatibility with Arduino shields, but in a smaller form factor thanks to its surface-mount design. It facilitates electronic prototyping and project development through its user-friendly programming environment and its input/output pins for connecting various components.

Note:
The Arduino Uno can be powered either through the USB connection (which provides 5 V, up to 500 mA) or through an external power supply. The power source is automatically selected by the board.
The external (non-USB) power supply can be either an AC-to-DC adapter or batteries. The AC adapter can be connected to the board's 2.1 mm DC barrel jack. Wires from a battery pack can be connected to the board's pins labeled GND (ground or 0 V) and VIN (positive input voltage).
In theory, the board can be powered with an external voltage ranging from 6 to 20 V. However, powering the board with less than 7 V may result in unstable operation, even though it may work at 5 V in some cases.
If you use more than 12 V, the voltage regulator may overheat or become damaged. The ideal recommended voltage range for powering the Arduino Uno is 7 to 12 V.
