The board version can be found on the board’s silk screen, for example:

 ![board_version](https://canada1.discourse-cdn.com/flex034/uploads/myriadrf/original/2X/9/94b5d0a12b7971314b30f315b098b9fa0e89a358.png)

The fact that LimeUtil does not recognize the board, suggests two possibilities:

1. the software is too old and does not have support for it. (You can check the software version with “LimeUtil --info”
2. the board was programmed with incompatible gateware and is not functioning properly.
