## Questions & Answers

**Q: Buenos dias, este sirve para arduino?**
A: Si, se conecta por USB

**Q: Comes with uart cable? or just usb?**
A: Mine came with the connector to the scanner itself that had bare wires attached. It let me connect directly to my project. It does not have any DB9 or DB25 if that’s what you are asking. A pigtail of individual wires was much more versatile. Yes, serial was one of them. I cannot guarantee what yours will have, I am not the manufacturer or distributor.

**Q: where can I found the full config manual?**
A: The unit comes with very basic manual, that provides an email to support for more in depth configurations. They answered all my questions thoroughly and fast, including sending the complete configuration manual with all the codes.

I would recommend this item and the manufacturer.
