GPIOs 34 to 39 are GPIs – input only pins. These pins don’t have internal pull-up or pull-down resistors. They can’t be used as outputs, so use these pins only as inputs: GPIO 6 to GPIO 11 are exposed in some ESP32 development boards.

Let’s take a closer look at the ESP32 pins and their functions one by one. ESP32 GPIO Pins. The ESP32 development board has 25 GPIO pins that can be assigned different functions by programming the appropriate registers.

2024年9月27日 · With a whopping 48 pins packed into this tiny chip, understanding each pin‘s function is key to harnessing the full potential of the ESP32. In this comprehensive guide, we‘ll walk you through everything you need to know about ESP32 pins. From GPIO to touch sensors, ADC to DAC, we‘ve got you covered. Let‘s get started!

ESP32 has four GPIO pins which can be used as digital input pins only. They cannot be configured as digital output pins. Also, unlike other GPIO pins, these pins do not have internally connected push-pull resistors.

2024年3月12日 · Here are the main types of pins you will find in the ESP32 pinout: Digital Pins: These pins can be configured as inputs or outputs, allowing you to read digital signals from sensors or control digital devices. Analog Pins: These pins enable analog input and output, allowing you to read and generate analog values for precise measurements or control.

Let’s take a closer look at the ESP32 pins and their functions one by one. The ESP32-WROOM-32 module has 32 GPIO pins that can be assigned different functions by programming the appropriate registers. There are several kinds of GPIOs: digital-only, analog-enabled, capacitive-touch-enabled, etc.

2023年11月13日 · Its pinout includes GPIO pins for digital, analog, and capacitive touch, PWM pins for precise control, I2C pins for communication with compatible devices, SPI pins for high-speed serial communication, and UART pins for asynchronous serial communication.

2024年5月16日 · This article on Esp32 pinout reference gives a complete idea about the pinout configuration, the function assigned to pins, what gpio pins we can use. Esp32 chip has 48 pins with multiple functions. Not all the ESP32 development boards have all the pins exposed, and there are some unusable pins.
