Hi, I just received my NanoVNA. I am using Martin Svaco's excellent Beginner's guide to get acquainted with its operation.
I want to upgrade my firmware if there is an upgrade available. But I am confused what model to look for and where to get the dfu file. My unit looks like sandwiched circuit boards open to the side. Looks to be 2.8 inches. Is this a clone of the original? When I tap Version it says NanoVNA at the top. , based on edy555 design. Version 0.7.1-2-g5a10105, build time May 8 2020, Kernel 4.0.0
Could someone please help direct me?
Thanks, Michael
