Whenever I buy an arduino for a project now, I get an elegoo. All my creations run on them. I think this is the cheapest they get without having to visit dodgy Chinese websites to install the drivers. I've had one hooked up to a permanent project that's plugged in 24/7. It's been months now, no issues at all. Fantastic value.
I also like the fact that the various pin names are printed clearly on the Dupont connectors along both sides of the board, making careless connection mistakes less likely and is one of the main reasons I chose this make of board over another similarly priced unit. They also include a little card with a link to what they call a tutorial for all the OS platforms, though which is actually an installable version and a zipped version of the Arduino IDE. Not all board manufacturers make it easy by including such a link with some expecting you to contact them but with no instruction to do so when you buy their board. Perhaps they believe in ESP and hence you will know what to do :)
All in all I'm well pleased with this UNO and looking forward to some playtime with it over the weekend.
ORIG: It arrived, packaged pine, but it was not recognised by Win7 when I connected via USB. I did some googling and it seems the bootloader is not loaded to the arduino. The only way to load the bootloader is via another working arduino. So I will return this one.
UPDATE: I just ordered a second (how stupid am I), the second one also does not work! I noticed the first board looked like it had the official USB controller chip (QU18 or something), but this one had something different (a1shr and another chip has AMS1175.0 Q1818). I will return the second one - I won't buy another. This board is probably good if you are already an expert with Arduino's and can load a bootloader to it (you need another working arduino to do that I believe).
UPDATE2 (same day to update 1): So - I got it working. Download Arduino IDE and save to desktop. Go to Device Manager, Right Click on Unidentified Device, Update Drivers, browse to the Driver sfolder of the Arduino download (I downloaded the zip and saved to program files), then let windows do it's thing (I didn't specifiy any particular folder, just pointed it at 'drivers' in that arduino folder I downloaded from the official site), then it worked. Device shows up as arduino, and the IDE blink test works (note the LED was blinking all the time anyway, so I changed the blinktest value to 10seconds, 10000 so i knew it had uploaded). Now to have some fun!
I am very impressed with these boards, hooking up to the PC I had no issues testing the blinky example and serial port example. I will definitely be buying more of these as the price is great and the quality is excellent.
