Kuman UNO R3 Board ATmega328P with USB Cable - Compatible With Arduino UNO R3 Mega 2560 Nano Robot for Arduino IDE AVR MCU Learner K53, Blue Review

Seems well done. On closer inspection, there is no bad soldering to be seen. The bushings at the top are properly aligned. More importantly, they keep the jumpers tight. Everything looks neat except for the power connector which is a bit off, but that doesn't bother me. Defined by Windows as Uno R3 immediately after connection. I downloaded a few programs and everything worked fine. It's a clone but looks and smells like the original; OK, it doesn't smell.

I bought several of these for different purposes. One thing I made is a small meter that shows the volume on my home theater receiver since the receiver is in a closet where I can't see the display. The other is the motor temperature monitor for my 3D printer. The Arduino is pretty much standard hardware at the moment, but for the price-performance ratio it's a good choice. As I think about it, I should probably add a few more of these to my cart.

When I connect the Arduino to my laptop, the ON and L LEDs are on, my laptop doesn't recognize the Arduino and the Arduino IDE doesn't recognize it. I tried connecting this Arduino with different cables, different ports and even different laptops. All had the same result: 2 LEDs lit up and nothing showed up in the device manager. My other Arduino works fine and is recognized, but this Arduino doesn't work properly. I can't even code it because of this problem. A note from the seller to fix this

I bought two of these, one as a set and one separately (this item). I also have some original Arduino Unos. This device is good. The build quality is not perfect, but acceptable. The pin headers are not perfectly aligned, the power connector is slightly misaligned, and the soldering part is inconsistent. BUT IT WORKS. I am very happy with the purchase, I will probably buy more. If you want undeniably superior build quality, buy a real Arduino. If you're okay with "just enough" for less than…

I ordered two Kuman UNO R3 ATmega328P boards with USB cable. They arrived on time as promised. The devices were well packed. I have opened and inspected the boxes and found them to be in very good condition, all parts fit very well. I've already programmed my device that I bought from Radio Shack about two years ago and use as a development module. So all I had to do was load my sketch into these two modules and incorporate them into projects I made for some friends. Everything worked as…

I just don't understand how you can make such boards at such a price - you can't even buy spare parts for the cost of this board. I've seen a few reviews mentioning questionable soldering or assembly, but the board I received looks and works great. Previously cheap clones used a CH340 serial interface chip which required special drivers - this clone looks like an exact copy with an M16 AVR chip and therefore works exactly like the official version. It comes with a BLINK test program that runs…
