This is slightly above the ESP32’s recommended ADC input range (0–3.3V) — so there may be risk of overvoltage. The actual safe range depends on the specific ESP32 board (some tolerate up to 3.6V), but this is borderline.
is 33K the right resistance for the bottom r?
Custom pin selection (GPIO35 for SDA and GPIO34 for SCL) is unusual — those GPIOs are input-only on many ESP32 boards. If this works, it may be a board-specific configuration or a misunderstanding (we'll verify when reviewing the code).
