UNO R3 Board ATmega328P with CH340G Chip Compatible with Arduino UNO R3 Mega 2560 Nano Robot for Arduino IDE AVR MCU Learner K53,with Straight Pin Header and USB Cable

The most important thing for my use was that this was Arduino compatible. Sometimes boards like this are not and you just have to guess or order it and try it. I had no problem with this board being compatible.Everything came packaged well and looked as if it would work fine. It came in an anti static bag which is important.I like that it came with a few extra pins.

This is a really good board with zero fitment issues. I put it in a case and paired it with a DIN breakout bracket and it fits like a glove. No issues in performance neither. For the price this is a good deal. Comes with a cheap but working USB A/B cable, which feels a bit dated these days. I like the chunky full size connectors even though. Five stars from me. I hope this helps to make a decision.

I tried various IDE's and COM(CH340G) settings for all the typical uno boards and none of them could get the board to even "auto blink". Could have been a bad board...don't know!!

This is your basic Arduino Uno clone. I powered it up, ran a few sketches, and everything worked fine. The Uno design is open source, so you get a lot of manufacturers selling a pretty high quality board that’s almost identical to the original. There are a few things to note on this one:1) The Atmega 328P chip is the surface mount type. If you want the version with the removable DIP 328 chip, you’ll have to spend a few dollars more for another vendor. I highly recommend owning at least one UNO with the DIP socket, so you can use it as a programmer for other DIP 328 chips (if you ever want to use them outside of the UNO board, or swap chips to swap programs). I’m not knocking off any stars for this, I just want to help other customers be aware of the differences.2) This board uses the super common (on non-official Arduino’s at least) CH340 chip for the USB interface. Supposedly you may need to search the web for a tutorial on how to download and install the driver for this chip so that windows can recognize it. I have literally NEVER had to do this, and I’ve used boards with CH340 all the time, on many different systems (Win 10, 11, Linux). When I plugged in this UNO, the PC recognized it easily without any extra work on my part.3) It comes with some header pins, if you need them. Most Uno’s don’t include these, so this is a nice addition. It also ships in an anti-static bag, in a cardboard box so it doesn’t get shocked or smashed in transit.4) It comes with an old school USB-B printer cable for programming, just in case you don’t have an old one laying around. Unfortunately, it’s a super short 12 inch cable! I’ll definitely be using my own.The Arduino Uno is a classic board that’s starting to show its age relative to more modern microcontrollers that are far more capable (mostly larger memory, faster processors) for about the same price, or less. But it’s also super simple to use, very forgiving of mistakes, has a lot of GPIO pins, a lot of GPIO types, and is very easy to learn if you are a beginner. It has a huge support community and thousands of project tutorials online and hundreds of accessories (shields, sensors, etc.). I have several other more modern microcontrollers, but I find myself going back to the good old UNO time and time again.Final Rating: 5 stars! A classic board, at a fair enough price, that works well.

The reason for the low rating on easy to use is because this board uses a different chip to communicate with your computer, a CH340. If you're running Windows, you will likely have to look for and install a CH340 driver to run it. If you're running Linux, please note that the CH340 Kernel module is broken, and you will have to download, compile, and install the CH34X patched driver yourself from Github, (which is really not too difficult to do). The hard part was spending all day researching the issue why it wouldn't connect via USB0. If you want to avoid the extra work, do NOT buy a board that mentions "CH340" in the description. Now, I finally have it flashing LEDS. I'm satisfied. It's 2:00AM. I'm going to bed.

Flashes easily with the arduino software, which is more than I can say for so many of these boards. Seems to be working very well and has been in use for a few weeks for a project without being turned off. Pinout is entirely compatible, and it seems very high quality.

There's not really anything that makes this special compared to there UNO R3 boards. I have Official ones made by Arduino and 3rd party ones like this and other than superficial changes there's really no difference.The pin header is a nice plus, I feel like I never have enough of those. But I wouldn't buy this one just because it has the pin header if you can find an UNO for less money.

I've been professionally developing for embedded systems for a lot of my career, but I haven't had the opportunity to work with the small commercial controllers (Arduino, Raspberry Pi, etc). I saw this and, at the price, I had to jump on it. I don't have a lot of experience with this controller, so everything is completely new to me. Since there are no instructions included (minus one star!), I've had to google every step of the way, from figuring out how to develop for the board to how to download the programs (or scripts, as they are called here). Working with the Arduino is completely different from how I develop for industrial systems. I'm not yet proficient at this, but I'm experiencing the same feeling of excitement and awe as when I first started working with computer systems, many (many!) hears ago. I'm having a great time and highly recommend this board to anyone who wants to relive the excitement of exploring new technologies, making lots of mistakes and learning a whole lot on the trip. Enjoy the adventure!
