Reliable clone for student projects
Bought five of these for a university robotics club. All of them performed consistently. The pinout matches the standard R3 layout perfectly.

Perfect for beginners and prototyping
This board works flawlessly with the Arduino IDE. The CH340 driver was easy to install on Windows 10. Great value for the price compared to official boards.

Great performance, USB cable not included
The board functions great, just be aware you need a USB A to B printer cable which isn't included in the package. Otherwise, no complaints.

Exactly what I needed to start learning
As someone new to microcontrollers, this board made getting started very easy. Plenty of tutorials online work directly with this hardware.

Good quality, minor driver hiccup
The board itself is solid and all pins tested working. Had a small issue finding the right driver initially, but once installed, it uploaded sketches without errors.

Stable and fast shipping
Used this for a home automation sensor node. It has been running stable for three weeks now. Highly recommend for IoT prototypes.
Q: Does it support 3.3V logic levels?
A: The board operates at 5V logic levels. While it has a 3.3V output pin, the I/O pins are not 5V tolerant if connected to 3.3V systems without level shifting.
Q: Does this board come with a USB cable?
A: No, the package includes only the UNO R3 board. You will need a standard USB Type-A to Type-B cable separately.
Q: Is this compatible with Mac OS?
A: Yes, it is compatible with Mac OS. You may need to install the CH340 drivers, which are available for download from our support page or the manufacturer's site.
Q: Can I power this board with a 9V battery?
A: Yes, you can power the board via the barrel jack connector using a 7-12V DC power supply, such as a 9V battery adapter.
Q: What is the difference between this and the official Arduino?
A: The main difference is the USB-to-Serial chip. This board uses the CH340 instead of the ATmega16U2 found on official boards. Functionally, they operate identically for most projects.
