UNO R3 Board ATmega328P with USB Cable(Arduino-Compatible) for Arduino, Input Voltage 7-12V, 16MHZ,14 Digital 1/0 pins Support PWM, SRAW 2KB, Compatible with RPi 4B/3B+/3B/2B/B+/Zero/Zero W

I picked up one of these to control a 12vdc windshield wiper motor that wasn't cut out for the job of powering a Country Living Grain Mill. The motor would get very warm after 5 minutes of grinding.I used this board to program a button which would begin pulsing the motor for 2 minutes running, 1 minutes resting. It worked like a charm to fix the issue on a budget.Ended up upgrading the motor so I didn't need this anymore, but I was able to learn a lot about low-voltage wiring and simple coding. I would highly recommend this board for simple automation.

Great alternative to brand name, price is fair. I've had no issues with compatibility or otherwise while using this.

wonderful board, easy to connect once i installed the driver to make it compatible with my windows 11, very good for the money, nice size for small Arduino projects. compatible with most computers.

Bought this to use for testing code intended for another (genuine Arduino) board that is hard to access. My test code would run for a while, a few seconds to maybe a minute, then the serial monitor would either freeze, or go into "insanely fast loop", ignoring any delay() or millis() timing commands. A close look at the simple Blink sketch revealed that even when running "normally", a one-second delay would take anywhere from 960 to 1040 milliseconds, before the program crashed. I'll buy genuine Arduino from now on.UPDATE: I did not expect a refund for this item as it was too long since I had purchased it. But the seller reached out to me after my 1-star review and offered a full refund. Very unexpected for such an inexpensive item. Increasing my review to 3 stars due to seller's response. Maybe I just got a lemon.UPDATE #2: Seller reached out to me AGAIN, doing everything they can to make it right. I am increasing my rating to a 4 given their outstanding effort.

It worked as well as any other branded Arduino board.

Got this yesterday, 5/29/25. Hooked it to computer, WIN 11, IDE 2.3.6. Unit powered up like a charm, no bootloader or driver problems. Loaded blink fast sketch from example folder, worked flawlessly, played with timer settings, took everything in stride. Will buy again!

Doesn’t work out of the box. LEDs light but there is no communication with the Arduino IDE. Awaiting feedback before initiating refund.

Loves me an arduino. Tons of fun.
