What is the difference between Arduino Uno SMD and R3?

The Arduino Uno R3 comes in two models; the normal version and the SMD version. In the SMD version you have the Atmega328 controller IC as an SMD chip soldered into the board, whereas in the normal version the IC is held on, the Arduino by an IC Holder. The better option for beginners would be the Normal version.

Is Arduino Uno and Genuino Uno same?

Both sides started making their own variants of boards, with some only available from the USA (Arduino) and others only outside the USA (Genuino). Since they have patched up their differences now the two boards are one and the same. A Genuino Uno and an Arduino Uno are the exact same board.

What is Uno R3 SMD?

Overview. The Arduino Uno Rev3 SMD is a microcontroller board 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 ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header, and a reset button.

What is UNO SMD?

Overview. The Arduino Uno SMD is a version of the Arduino Uno, but uses an surface mount version of the Atmega328P instead of the through-hole version. “Uno” means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino, moving forward.

Why is it called Arduino Uno?

“Uno” means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases.

What does Arduino Uno do?

Arduino UNO is a low-cost, flexible, and easy-to-use programmable open-source microcontroller board that can be integrated into a variety of electronic projects. This board can be interfaced with other Arduino boards, Arduino shields, Raspberry Pi boards and can control relays, LEDs, servos, and motors as an output.

What is SMD in Arduino?

Overview. The Arduino Uno SMD is a version of the Arduino Uno, but uses an 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 (datasheet).

Which microcontroller is used in Arduino?
