The sensor has two channels: 50A and 200A channels.

On the 50A channel, there is a Schottkey diode with a 0.13V voltage drop, but on the 200A channel there is no diode in-between.

Both channels run through a 5k1/10k voltage divider for diving 5v->3v3, so STM32 ADC measurements use the divided voltage. Resistors are both 1% tollerance, so accuracy is fine.
