ESP32-s3 3.3v monitoring

Postby jjones7432 » Fri Mar 22, 2024 7:09 pm

I've searched the forums for any methods for esp32s3 chip input voltage (3.3v) monitoring and found nothing. I assume this would be a common issue for battery powered applications. So I have two questions :
1. Is there a API function specifically for monitoring the esp32s3 3.3v chip input?
2. if not, is there a recommended method to implement voltage monitoring?

if not, I'll build the functionality using the APIs for ADC.

Thanks.

You can use one of the ADC channels available on the ESP32-S3 to measure the voltage. Connect the input voltage (3.3V in your case) to one of the ADC pins, and then use the ADC API to read the voltage.
