Overview
The Arduino UNO Rev.3 board 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 crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.

Frequently Asked Questions
What's the difference between this SMD version and the classic Arduino UNO?
The core specifications are identical — the difference is in the chip packaging. This board uses a surface-mount (SMD) ATmega328P instead of the classic through-hole DIP chip, which typically makes it more affordable while keeping the same performance.
Does this board need special drivers to work with my computer?
Yes, since it uses a CH340 USB-to-serial chip rather than the original FTDI/ATmega16U2 chip found on genuine Arduino boards, you may need to install a CH340 driver on Windows before it's recognized. Mac and Linux typically detect it automatically.
Is this board compatible with standard Arduino shields?
Yes, it follows the same form factor and pin layout as the standard Arduino UNO Rev3, so standard shields and accessories fit without modification.
Where can I find the ATmega328P datasheet for this board?
The chip used is a standard ATmega328P, and its full datasheet is publicly available from Microchip's website for detailed register and electrical specifications.
Do I need to buy a separate programmer to upload code to this board?
No — like a standard Arduino UNO, it can be programmed directly over USB using the Arduino IDE, no external programmer required. See the download link below.
