Devbattles Arduino Uno R3 Microcontroller Board Based + USB Cable

The units were well package. I opened the boxes and and inspected them and found them to be in very good condition with all the part mounted very well/Detected by windows as a Uno R3 immediately on connection. Downloaded a couple of programs and it worked perfectly. The construction is nice, it is compatible with all the libraries I've thrown at it and I'm extremely happy with it.

Great device. I bought 3 of these and they are my go-to controller for some pretty sophisticated DIY projects. If you follow basic principles and NEVER try connecting a pin to something for "trial & error" but instead, be certain of the voltage AND current potential that you are supplying (or demanding), and this beautiful device will work like a horse. When it comes to your connection to the computer, some Windows serial "portage" issues arise but it's a matter of persistence. I would just like to note that I am in no way sponsoring arduino, I just personally love their products!

I have used this product for several different projects within my business, and would recommend it to anyone looking to create a product requiring computing power. I was able to build and code the little example I have pictured in less than a day with this kit. Worth to purchase.

Great uno R3 board. Quality is as good as more expensive boards. Here is initial problem I had in case you run into the same thing. When trying to upload to board, would get a "upload problem error". Be sure to go to Tools / port and select the COM port that is showing(after you connect the board) . Because for some reason, the board changes ports from my other board( an Arduino uno R3 ). One uses COM5, the other COM3, dont know why. Once I found that, it worked perfectly.

this is an amazing product . I was able to build and code the little example I have pictured in less than a day with this kit.highly recommended this book to everyone

The kit arrived undamaged and tightly packaged. I have started going through some of the experiments. First off, all the hardware is fine, and the whole set is packaged nicely. The kit has a nice supply of interesting input and outputs. Switches and LEDs and such. However, it's basic toy stuff and just designed to show you how these things work. So far everthing has worked perfectly. If you are looking for a decent arduino kit, this would work nicely and the price was perfect. I would highly recommend!

All seems to be great. Great Uno R3 development board as described. Highly recommended!

It's worked perfectly as an UNO. Just what I'd expect. :)I tried it both with and without a shield - no problems. Connected to my Mac easily too.
