The {IDF_TARGET_NAME} chip features 21 physical GPIO pins (GPIO0 ~ GPIO20). For chip variants with an SiP flash built in, GPIO11 ~ GPIO17 are not led out; therefore, only 14 GPIO pins are available.
Each pin can be used as a general-purpose I/O, or to be connected to an internal peripheral signal. Through GPIO matrix and IO MUX, peripheral input signals can be from any IO pins, and peripheral output signals can be routed to any IO pins. Together these modules provide highly configurable I/O. For more details, see *{IDF_TARGET_NAME} Technical Reference Manual* > *IO MUX and GPIO Matrix (GPIO, IO_MUX)* [`PDF <{IDF_TARGET_TRM_EN_URL}#iomuxgpio>`__].

- SPI0/1: GPIO26 ~ GPIO32 are usually used for SPI flash and PSRAM and not recommended for other uses. When using Octal flash or Octal PSRAM or both, GPIO33 ~ GPIO37 are connected to SPIIO4 ~ SPIIO7 and SPIDQS. Therefore, on boards embedded with ESP32-S3R8 / ESP32-S3R8V chip, GPIO33 ~ GPIO37 are also not recommended for other uses.
- USB-JTAG: GPIO19 and GPIO20 are used by USB-JTAG by default. If they are reconfigured to operate as normal GPIOs, USB-JTAG functionality will be disabled.
