What is the max input/output voltage on the GPIO pins?

The ESP32-S3 is a 3.3V device. The voltage applied to a GPIO pin should never exceed VDD + 0.3V, or 3.6V for a 3.3V supply. The minimum should never be less than -0.3V.

Hey @J.a.m.e.s,
@Jeff105671 is correct in his answer. If you want a bit more information that datasheet Jeff linked contains a bit more information in section 5.1 (Page 63).
