Review: Really good Product - The quality of the product is very good. I am highly impressed with its performance. I found this board to be an excellent choice for projects.
Review: Arduino Uno R3, on the cheap - 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.

## Questions & Answers

**Q: Does it support jtag? Ejtag?**
A: Nope.  Not much JTAG support in the lower-end Arduino world.

**Q: What drivers do I need to install to get this to work?**
A: Install the open source Arduino Development Environment software on your computer. These board are 100% compatible with the standard Arduino UNO R3. You should be able to compile and upload your software to this board with no additional drivers being needed. Silicon Labs does have the USB to UART drivers available on their website just in case you run into an issue with the USB communications. This board worked just fine on my computer, but I already use Silicon Labs USB bridges for my other work. I may already have had their drivers installed so I did not see any issues.

**Q: where i can boy motor shield and Led dot matrix 8 * 16 for KS0470 model?**
A: Amazon.  Search “Arduino Uno Motor Shield”. Again Amazon and search “MAX7219”.
