Overall, I think I like the STM32 version better. I do wish it had the AFE of the 8051 version.

I suspect the STM32 version is newer.

Hi
not sure Danny will read this post so questioning the public :)
Regarding AFE, what would be the major benefit of using a dedicated diff-amp for V and I? To me, it looks like sharing a single diff-amp for both channels would be better as the same offset/bias will be applied... do I miss something?

I fully agree, it was a great meter, bad enough I destroyed it by stupid accident... On another side, if that would not happen, I would never learn about these devices' inner work  8)

Thanks, but in my case the stored energy was too high as AFE chip got fully shorted. I desoldered it and the meter may start, but then complain of an error and shutdown. I think the chipset datasheet is confidential for a reason, I am pretty confident by now that AFE side consists of a number of analog switches and diff PGA and probably would not be that difficult to substitute should we have a good chipset description...

The kind user Indman recommended this device to me. I already have a T4, but I would like to have a device that also reads the values ​​on the circuit, so this could be for me. Is it sold in different kits? I would like to have all the options available. I searched, but found very different prices. Any help? Thanks  ;)
