ESP32 vs STM32

[vnm1911]

Hello Viktor,

I want to design wearable ECG(Full ECG, not only heart rate)+SpO2+Temperature monitor from scratch. Could you suggest if I should go with ESP32 Microcontroller for my project or STM32 is best for wearable device projects? If I succeed my company want to go for FDA approval of the device also, so it has to most accurate. Also my senior may need to add Machine Learning algorithms too, to be implemented on/in Microcontroller only.
I will appreciate all your help and advice.Your YouTube videos are really BIG BIG help.

Thanks and Regards..
