GPIO & RTC GPIO [中文] GPIO Summary The ESP32 chip features 34 physical GPIO pins (GPIO0 ~ GPIO19, GPIO21 ~ GPIO23, GPIO25 ~ GPIO27, and GPIO32 ~ GPIO39). Each pin can be used as a general-purpose I/O, or be connected to an internal peripheral signal.

There are many questions on how to use the ESP32 GPIOs. What pins should you use? What pins should you avoid using in your projects? This post aims to be a simple and easy-to-follow reference guide for the ESP32 GPIOs. The figure below illustrates the ESP-WROOM-32 pinout.

GPIO stands to General Purpose Input Output, and is responsible to control or read the state of a specific pin in the digital world. For example, this peripheral is widely used to create the LED blinking or to read a simple button.

Learn about ESP32 Pinout along with in depth analysis of GPIO, ADC, DAC, Touch, SPI, I2C, UART, PWM, Power, GND and EN Pins.

Jun 30, 2022 · The most fundamental process in any embedded development is the usage of GPIO (general-purpose input/output) pins. In this tutorial, we will learn about ESP32 GPIO pins and how to program them as digital output pins. For demonstration purposes, we will build an ESP32 LED blinking project in VS Code with ESP-IDF extension.

Overview ¶ The ESP32 chip features 40 physical GPIO pads. Some GPIO pads cannot be used or do not have the corresponding pin on the chip package. For more details, see ESP32 Technical Reference Manual > IO MUX and GPIO Matrix (GPIO, IO_MUX) [PDF]. Each pad can be used as a general purpose I/O or can be connected to an internal peripheral signal.

Detailed functional specifications of generic ESP32 chip, including GPIO pinout and important considerations for using the ESP32 hardware.

In this Guide, we will cover ESP32’s GPIO programming, cautions, and important notes while using it.
