1. What is the difference between Uno and Uno SMD? 

In the UNO SMD (Surface Mounted Device) the microprocessor chip (ATmega328) is integrated and soldered onto the board; whereas the ATmega328 is DIP in the standard UNO (Dual In-line Packaged), which means that the microprocessor chip can easily be removed and replace if necessary. 

2. Why is Uno SMD better?

The Uno board is primarily used by beginners who can use it in electronics projects and for programming.  The Uno SMD is  extremely user-friendly while allowing for exceptional connectivity.

3. Where can we use the UNO SMD Board? 

The Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and is commonly used in Robot cars, Fingerprint door locks, Home Automation, and Security systems. 

4. What chip does Uno SMD use? 

The Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller. The board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced with various expansion boards (shields) and other circuits. 

5. Does Uno SMD have ATmega328? 

Uno SMD is a microcontroller board based on the ATmega328P.It has 14 digital input/output pins, 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header, and a reset button.
