Exceeded expectations
Fast shipping and the board arrived well-packaged. I've tested the analog inputs and PWM outputs, and they are accurate. Definitely buying more for future projects.

Reliable and affordable
I bought three of these for a classroom project. All of them worked out of the box. The pin layout matches the standard Uno perfectly, so all my shields fit without modification.

Solid clone for prototyping
While it's not an official Arduino, the build quality is surprisingly good. The soldering is clean, and the USB port feels sturdy. Perfect for prototyping before committing to more expensive boards.

Good quality, minor driver hiccup
The board itself is solid and all pins function correctly. I had to manually install the CH340 driver first, but once that was done, uploading sketches was seamless. Highly recommend for students.

Perfect for beginners!
This board works exactly as expected. It was easy to set up with the Arduino IDE and the CH340 drivers installed without issues on Windows. Great value for learning IoT basics.

Great starter kit component
As someone new to microcontrollers, this board made my first LED blink project very straightforward. The documentation online is plentiful, and this hardware supports all standard tutorials.
Q: Does it support 3.3V logic levels directly?
A: No, this board operates at 5V logic levels. If you need to interface with 3.3V sensors, we recommend using a logic level converter to prevent potential damage to the components.
Q: What is the difference between this and the original Arduino Uno?
A: The primary difference is the USB-to-Serial chip; this board uses the CH340G instead of the ATmega16U2 found on originals. Functionally, they operate identically for most projects, but this version is more cost-effective.
Q: Can I power this with a 9V battery?
A: Absolutely. You can connect a 9V battery to the barrel jack or the VIN and GND pins. The onboard regulator will step it down to the required 5V for the microcontroller.
Q: Is this compatible with the official Arduino IDE?
A: Yes, it is fully compatible with the Arduino IDE. You may need to select 'Arduino Uno' as the board type and install the CH340 driver if your operating system does not recognize it automatically.
Q: Does this board come with a USB cable included?
A: No, this package includes only the development board. A standard USB Type-A to Type-B cable is required separately to connect to your computer.
