Re: ESP32-S3-Mini ADC Vref

Actually i met with an same thing, here what i find even after you use the calibration it doesn't give you the proper voltage output, In microcontrollers max ADC offset count is 5 but in ESP32s3 it leads more counts, in my research i found out using ADC_Atteun_DB_0 is better in in terms of millivolt...
