Current GPIO is for {IDF_TARGET_NAME} beta3 version. {IDF_TARGET_NAME} MP version would have 2 more available IOs, and some pin functions are changed. The {IDF_TARGET_NAME} MP version will be updated later.
Current GPIOs are for {IDF_TARGET_NAME} beta3 version. {IDF_TARGET_NAME} MP version would have 2 more available IOs, and some pin functions are changed. The {IDF_TARGET_NAME} MP version will be updated later.
The {IDF_TARGET_NAME} chip features 27 physical GPIO pins (GPIO0 ~ GPIO26). 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>`__].
