That is an unknown clone. I've never seen that processor in one of these before BUT that doesn't mean it won't work.

The nanoVNA only uses about 30% of the internal peripheral ability of the chip (timers/FPU/memory/etc) as many areas/functions are not needed. I have attached a chart of the STM32F3xx family below and there are several subgroups to each product line as well. look here: However, the final say is up to you and personally, if the ad specs an STN32F303 and you didn't get that, I would return it as 'counterfeit'.

I purchased a "NanoVNA-H4" from Amazon in the UK. The brand is Hima, supplied by ANGLO CT. I purchased from Amazon to try to avoid delivery delays and unexpected import costs. I opened the back of the device to find there is no QR code or version no. But more significantly the mcu/processor is an STM32F 302. I understand the "302" part is a lower spec than that used by the official Hugen product. I don't "need" the device for immediate use, so should I return it? Thanks. |
