Hi,

Is the schematic available, so i can see how the battery voltage is connected?

Hi is the battery voltage sampled bu the STM32 or by the ESP32.
I would like to sample very fast to log the voltage waveform of a start the sd-card.

What is the number of bits for the sampled voltage, would it be possible to see the voltage ripple from the alternator in the sampled voltage?

Thanks ...
