Stable power delivery
I was tired of boards resetting when I activated servos. This enhanced version with the improved power regulation solves that completely. Highly recommended for anything involving motors.

Great board, minor pin labeling issue
The board works flawlessly for my robotics project. The dual motor driver support is a nice touch. Only giving 4 stars because the silk screen printing for the analog pins is slightly faint, but functionality is 100%.

Perfect for beginners and pros alike
This improved version of the UNO board is fantastic. The enhanced power supply handles my motor drivers much better than the generic clones I've used before. Setup was instant on Windows 10.

Solid upgrade from standard UNO
The build quality feels premium. The extra protection on the power input gives me peace of mind when experimenting with different battery packs. Works great with the Arduino IDE.

Best value for learning AVR
Bought this for my university embedded systems course. It compiles code quickly and the USB connection is very stable. The included headers were easy to solder on.

Exactly as described
Fast shipping and the board arrived well-packaged. It recognized my computer immediately without needing extra drivers. Perfect for my home automation prototype.
Q: Do I need to install specific drivers for Mac OS?
A: For macOS High Sierra and later, the board usually uses the built-in CDC ACM drivers and requires no additional installation. Older versions may need the CH340 driver if applicable.
Q: Is this compatible with the standard Arduino shields?
A: Absolutely. This board follows the standard UNO R3 form factor and pinout, so it is compatible with almost all existing Arduino shields.
Q: Does this board come with the USB cable included?
A: No, the USB A-to-B cable is sold separately to keep the base price low, but any standard printer cable will work perfectly.
Q: Can I power this directly from a 9V battery?
A: Yes, you can connect a 9V battery to the barrel jack or the Vin/GND pins. The improved voltage regulator handles this range efficiently.
Q: What is the maximum current the 5V pin can output?
A: When powered via USB, the 5V pin can supply up to 500mA. When using the barrel jack, it depends on your external power source, but the regulator is rated for 1A max.
