Why we need to stay away from the esp32 modules?

[@Zachariah-Peterson]

I'm not telling people to stop using ESP32, just that STM32 might be better for this project because it's for an industrial application.

​@@Zachariah-Petersonbut why is stm32 is better for industrial applications

[@zyeborm]

​@@amarigannoyunu587perhaps the thermals? But you can get higher temp esp32s I believe

[@AgentDexter47]

@@amarigannoyunu587So generally many known brands like STM, AVR, PIC and NXP do studies that show component reliability, and failure rates. In general if you are not doing anything important, ESP is okay. But ESP should never be used for anything where it controls any actuator where someone could get hurt. Anything industrial should at least follow IEC 61508

​@@amarigannoyunu587 Certifications, guarantees, docs, internal blocs, Hal, etc. Don't know exactly but the ARM core and stm32 tools seem more stable if I'm not wrong.

Swap 3 and 4 as in S G G P?

[@ezion]

Great insight! Thank you.

[@daniel38535]

Why don’t just swap the ESP32 module for a more recent version ? There are plenty of modules from reputable distributors with FCC and all requiered certifications.

[@Zachariah-Peterson]

I mentioned the STM32 option because this project is for an industrial sensor. If you wanted to use an ESP32 module then go for it.

[@zyeborm]

​@@Zachariah-PetersonI think people are wondering what the specific reason for going stm rather than esp that you have in mind? Is it just longer history? Thermal? It's there something else?

My manager makes me do L1 - F.Cu (sig/GND flood) L2 - Int1 (sig/GND flood) L3 - Int2 (sig/GND flood) L4 3V3 plane L5 5V plane L6 12V plane L7 Int 3 (sig and GND flood) L8 45V plane L9 60V plane L10 120V plane L11 N8V plane L12 GND plane With stitching GND vias around perimeter. I think this is a terrible stack up but he gaslights me if I refer to Altium Academy suggest stsckups. He always rejects the ide that the energy flows in dielectric (and that traces are ineffect wave guides)

[@Zachariah-Peterson]

How many times as your manager produced a product that fails EMC testing? Once he does that enough then he won't be your manager anymore!

[@TheVideoVolcano]

@@Zachariah-Peterson None that he's told me. He has produced 100s of boards and background is night vision/thermal imaging. He says we are only low frequency so there is no need for "Faraday cages".
