    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.

    After spending 4x this on a brand version and then buying this version, I honestly cannot tell the difference in performance. It is very well made and just as good as the official Arduino Uno.
