## 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”.
