=======================================
Michael for clarification,
BH5HNU hasn't claimed that deepelec's NanoVNA-F is the official version, only that deepelec is the "official store" for its versions 2.3 and 3.1 NanoVNA-F products. BH5HNU was previously employed as a NanoVNA-F designer at SYSJOINT. He left because of differences with them. SYSJOINT can lay claim as the official store for its version 2.5 NanoVNA-F, which of course BH5HNU helped produce and adheres to the original open source design.
There are bad clones of the NanoVNA-F on the market which have deviated from the original design. Those bad clones generally do not have metal cases or the massive battery of the original NanoVNA-F. BH5HNU has not called the NanoVNA-F ver 2.5 product from SYSJOINT a clone or bad product.
The new 2.3 and 3.1 NanoVNA-F from BH5HNU at the deepelec store have upped the ante and, in my opinion, given BH5HNU a completive advantage over SYSJOINT. Additionally, BH5HNU has continued to release firmware updates for the NanoVNA-F which SYSJOINT has not done.
