Solid budget option

Bought five of these for our workshop. They all function correctly. The only downside is the USB cable included feels a bit flimsy, but the board itself is great.

Good quality control

The soldering on the pins is clean and the board layout matches the standard Uno R3. Upload speeds are consistent. A reliable choice for prototyping.

5 FAQ

Q: Does this come with a USB cable?

A: Yes, the kit typically includes a standard USB Type-A to Type-B cable for programming and powering the board. Please check your specific package contents upon arrival.

Q: Do I need to install specific drivers for this board?

A: Yes, since this board uses the CH340 USB-to-serial chip, you will need to install the CH340 drivers. They are available for Windows, macOS, and Linux and can be found easily via a quick search or on the manufacturer's website.

Q: Is this board compatible with the official Arduino shields?

A: Absolutely. This board follows the standard Arduino Uno R3 form factor and pinout, so it is fully compatible with most shields designed for the Uno.

Q: What is the difference between this and the original Arduino?

A: The primary difference is the USB-to-serial converter chip. The original Arduino Uno uses an ATmega16U2, while this compatible board uses the CH340. Functionally, they perform the same tasks, but the CH340 requires a separate driver installation on some operating systems.

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 pin. The onboard voltage regulator will step it down to the required 5V for the microcontroller.
