The ESP32 chip features 40 physical GPIO pads.

The IO_MUX, RTC IO_MUX and the GPIO matrix are responsible for routing signals.

This chapter describes the signal selection and connection between the digital pads (FUNC_SEL, IE, OE, WPU, WDU, etc),

256 peripheral input/output signals (control signals: SIG_IN_SEL, SIG_OUT_SEL, IE, OE, etc),

fast peripheral input/output signals (control signals: SIG_IN_SEL, SIG_OUT_SEL, IE, OE, etc),
