Thank you for the clarification.
Can I use one of the spare ESP32-S3 GPIO pins directly as a digital pulse input for the YF-B10 flow sensor?
The sensor generates approximately 450 Hz at maximum flow.

The sensor generates approximately 450 Hz at maximum flow.
Specifically:
- Which spare GPIO pins are accessible and suitable for pulse counting?
- Can these GPIO pins be used with ESP32 PCNT hardware in ESPHome?
- Is there any onboard filtering or protection that would affect pulse counting?
