What information can you pull from the OBD-II plug?

Hello, I have a 2002 Blazer, and I'm looking into if it would be possible to get the speed, rpm, battery voltage, etc information from the OBD-II port?Thanks

All of that information is available. You will need a compatible reader to interpret and display the information.

That should be able to read the information. I have never heard of the manufacturer. My Scantool.net OBDLink MX works great and I haven't heard many bad reviews for them, but it isn't a budget reader. They used to have a reader for ~$30, but I don't see it anymore.
