Reliable and authentic
I've bought clones before that had driver issues, but this original board connected instantly on Windows 10. The ATmega328P chip is clearly marked, and the soldering is clean. Great for prototyping IoT projects.

Solid performance
No complaints about functionality. It handles multiple servos and sensors without resetting. Took off one star only because shipping took a bit longer than expected, but the product itself is perfect.

Great board, slightly pricey
The performance is flawless and it's definitely genuine. My only hesitation is the price compared to compatible boards, but for critical projects where stability matters, paying extra for the original is worth it.

Perfect for beginners and pros alike
This is a genuine Arduino Uno R3 board. It worked straight out of the box with the IDE. The build quality is solid, and all pins responded correctly during my initial tests. Highly recommended for anyone starting with embedded systems.

Standard for a reason
The Uno R3 remains the gold standard for development boards. This unit has consistent voltage regulation and the USB interface is robust. I use it for debugging sensors before moving to custom PCBs.

Essential for learning coding
Bought this for my high school robotics club. The documentation online is vast, and since this is the real deal, every tutorial we followed worked without modification. Very happy with the purchase.
Q: Is this compatible with the Arduino IDE version 2.0?
A: Yes, the Original Arduino Uno R3 is fully compatible with Arduino IDE 2.0 as well as legacy versions like 1.8.x. You just need to select 'Arduino Uno' from the board manager.
Q: Does this board come with a USB cable included?
A: No, the package typically includes only the Arduino Uno R3 board. A standard USB Type-A to Type-B cable is required separately to connect it to your computer.
Q: How do I verify if this is an original board and not a clone?
A: Original boards usually have high-quality printing, a specific holographic sticker on the box (depending on the distributor), and the ATmega16U2 chip for USB handling. Clones often use CH340 or CP2102 chips which require different drivers.
Q: Can I power this board with a 9V battery?
A: Yes, you can power the board using a 9V battery by connecting it to the barrel jack or the Vin and GND pins. The onboard regulator will step it down to the required 5V.
Q: What is the maximum current I can draw from the 5V pin?
A: When powered via USB, the 5V pin is limited by the USB port (usually 500mA). When powered via the barrel jack, the limit depends on the regulator, but it is generally safe to draw up to 400-500mA total for the board and external components.
