I read that ESP32 has two pins named commonly as SENSOR_VP and SENSOR_VN or ( GPI36, SENSOR_VP, ADC_H, ADC1_CH0, RTC_GPIO0 & GPI39, SENSOR_VN, ADC1_CH3, ADC_H, RTC_GPIO3).
This looks it is a differential amplifier. But to to make it work in Arduino IDE or using Eclipse ?
How to adjust gain ?
Are there any examples available showing use of this preamp ?
