Great starter board
Easy to set up and start coding. The documentation online is plentiful. Took off one star because the USB cable wasn't included, but that's standard nowadays.

Compact and powerful
Fits perfectly into small enclosures. The build quality is solid, and the soldering joints look clean. The CH340G chip is much more reliable than older FTDI clones I've used.

Reliable for classroom use
Bought ten of these for our robotics club. They are robust and the improved version handles multiple serial communications beautifully. Highly recommended for education.

Perfect upgrade for my projects
The ATMEGA328PB offers extra USART and SPI interfaces compared to the standard 328P. The CH340G driver installed instantly on Windows 10. Great value for the price.

Excellent connectivity options
Needed the extra hardware serial ports for a sensor project. This board delivered exactly what was needed without requiring software serial libraries. Fast shipping too.

Good board, minor pin labeling issue
Works flawlessly with the Arduino IDE. The only downside is that the silk screen for the extra PB pins is a bit small, but once you have the pinout diagram, it's easy to use.
Q: What drivers do I need for Mac OS?
A: For macOS, you will need to install the CH340/CH341 serial driver. It is available for free from the manufacturer's website or via Homebrew.
Q: Is the bootloader pre-installed?
A: Yes, the ATMEGA328PB comes pre-loaded with the Arduino Nano bootloader, so it is ready to use immediately with the Arduino IDE.
Q: What are the main differences between 328P and 328PB?
A: The 328PB adds a second hardware UART (Serial1), an additional SPI interface, and two extra ADC channels compared to the standard 328P found in older Nano boards.
Q: Can I power this board via the VIN pin?
A: Yes, you can supply 7-12V DC to the VIN pin. The onboard regulator will step it down to 5V for the microcontroller.
Q: Does this board support 3.3V logic levels directly?
A: No, this board operates at 5V logic levels. If you need to interface with 3.3V sensors, please use a logic level converter to prevent damage.
