Hi. I have a hp finguerprint module reference ls200uv-7a2. Can someone tell me how to connect it to the arduino one r3
thanks to all

That's a laptop peripheral, probably not the right interface for a microcontroller - can you find a datasheet for it?
The problem is that I do not find information or do not know where to look.
The *fingerprint-reader you have there uses USB-interface.
Unless you got documentation from the vendor, SDK etc. to use the module, USB-host shield etc. - forget it. It will not work with Arduino.
Probably a single "scan" requires more memory than the simple Arduino has, so impossible to use it.
The fingerprint-modules that work with Arduino are very "intelligent" themselves - they do all the image processing internally and the Arduino doesn't have to do any heavy lifting.
