KEYESTUDIOV4.0 Development Board for Arduino UNO R3 with USB Cable

It's an Arduino UNO V3... not much else to say about that except that it works as well as every other UNO I have from every other company that makes them.Two things about this board set it apart from the rest. They are subtle details, to be sure, but they make a BIG difference.One is the printing on the board is high contrast. The board is black. The V3 connectors and the pin labels on the board are bright yellow. It is much easier to see than black printing on a blue board. The printing itself is crisp and can be easily seen.Two is socket for the ATMega chip. It's a little easier to get the chip in and out than sockets used on other boards. I realize that most IC sockets have a life of around 10 insertions but this one seems a little tougher. The reason this is important, to me at least, is that I use the board to develop sketches then move the programmed chip to a PCB, usually for my robotic drone projects. Weight in a drone is critical and anything you can do to save a few grams here and there can dramatically improve flight duration. All you need to run an Arduino Uno sketch is a programmed ATMega chip, a 16mhz Xtal, and a couple of 22-pf capacitors. You don't need the whole board. (Caveat: you also lose some of the circuit protections that the boards provide, especially when it comes to overvoltage. It is very easy to fry an ATMega chip if you make a wiring error.)Just a quick note: I eventually replaced the fixed socket with a ZIF socket (Zero Insertion Force, also available from Amazon for a good price). Individual ATMega chips can be purchased here in a 10-pack but I would not recommend doing that until you are very comfortable with DIY circuit making. Once you are, however, your project world will open up like you never imagined and you can take your next steps to truly become a Maker.Build a bunch of projects! Learn and have fun!

Work as well as real Arduinos and at a third of the price.

I bought this for my 10 year old at the time and he got a little confused but then he looked online for a driver and now it works fine!

I saw this for $9 and figured why not. I figured worst case, I could at least use the 'Atmega328p' which run about $13 to $15 for two anyway. It works great! I ended up using it to prototype my design instead of my Arduino Mega and when I was done, I actually loaded it with the "Arduino as ISP" sketch and used it to flash two breadboarded AVRs. This comes nicely packaged, a box inside a box, and includes an 18" USB cable. I also think the Black/Yellow is a nice change from the usual blue or all black PCBs. The top layer screening isn't as good as the original Arduinos or more expensive clones but you can still read the lettering.

The media could not be loaded. Initially the Keyestudio board was not recognized on WIN10. After checking some of the reviews, and updating the CP2102 driver, it worked perfectly. Although the pin descriptions are written on the board, I would prefer if the pin descriptions were also written on the headers as well. All-in-all a great development board at a great price.

My old Uno R3 found it's way into permanent service in one of my projects, so I got this to be my new experimentation board. When I plugged it in, I couldn't get my coding IDE to detect it as a board. Took me a while to figure out what the problem was, but I ended up needing the CP210X USB to UART bridge VCP driver from Silicon Labs to get windows to see this board correctly. A google search of those words should get you what you need, if you have the same problem I did.Beyond that, it functions as it should, and looks really nice in black and yellow.

Read what you are getting and cross reference. Did not work for what I was tring to do but wow now what I can do. If you think it make work worth a chance.. read. Worth it if you experiment

BOUGHT 2 OF THESE AND THE USB PORT IS NOT RECOGNIZED.
