Solid board, minor pin labeling issue
The functionality is excellent and it connects immediately. My only small complaint is that the silk screen printing for the pin numbers is slightly faint, but once you know the layout, it's not an issue.

Reliable replacement for original boards
I bought three of these for a classroom project. All three worked out of the box without any issues. The build quality feels sturdy and the USB port is tight enough to hold the cable securely.

Excellent compatibility with sensors
I have tested this with various I2C and SPI sensors, and communication is stable. The voltage regulation seems accurate, providing a steady 5V output for my peripherals.

Perfect for beginners and pros alike
This board works flawlessly with the Arduino IDE. The CH340 driver was easy to install on Windows 10, and I had my first LED blinking within minutes. Great value for the price.

Good performance, fast shipping
The board performs exactly as expected for an ATmega328P based system. I used it to control a small DC motor driver and it handled the PWM signals smoothly. Shipping was faster than anticipated.
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, which includes standard 9V batteries. Alternatively, you can use the VIN pin.
Q: Does this board come with a USB cable included?
A: No, the package typically includes only the development board. A standard Mini-USB or Micro-USB cable (depending on the specific batch) needs to be purchased separately.
Q: Is this compatible with the official Arduino shields?
A: Yes, this board follows the standard Arduino Uno R3 form factor and pinout, making it fully compatible with most official and third-party Arduino shields.
Q: Does this support 3.3V logic levels directly?
A: The board operates at 5V logic levels. While it has a 3.3V output pin for powering sensors, the I/O pins are 5V tolerant but not 3.3V native. Use a level shifter for 3.3V-only devices.
Q: What driver do I need for macOS?
A: For macOS, you usually need to install the CH340 or CH341 serial driver. Links to the drivers can be found on our support page or the manufacturer's website.
