Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Hello all.

Have someone tried to upgrade MCU there?
It will need firmware update, but from PCB layour perspective it is possible to just replace the MCU there to STM32F411C[EC] with one pin change.

Thank you.

I have made a mistake in previous email.
I am talking about STM32F411C[EC] MCU.
