With the ESP32, you can use any GPIO that can be input for the TRIG pin and any GPIO that can be output for the ECO pin. For example, you can use GPIO 26 and 27. Regards,

Mar 21, 2023 · Learn how to use the GPIO pins of your ESP32 board correctly with this single-page guide. Avoid bugs and improve your DIY projects with ease thanks to this ESP32 Pinout diagram.

ESP32 SPI Pins. ESP32 features three SPIs (SPI, HSPI, and VSPI) in slave and master modes. These SPIs also support the general-purpose SPI features listed below: 4 timing modes of the SPI format transfer; Up to 80 MHz and the divided clocks of 80 MHz; Up to 64-Byte FIFO

Learn about ESP32-WROOM-32 Pinout along with in depth analysis of GPIO, ADC, DAC, Touch, I2C, SPI, UART, PWM, RTC GPIO, Strapping, Power, and Enable Pins.

May 16, 2024 · 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.

Explore the comprehensive ESP32 Pinout guide. Learn how each ESP32 Pin works and which pins you should use. ESP WROOM 32 pins explained.

Strapping Pins: Affect boot mode and flash settings. Ensure external circuits don't interfere during boot. Input Only Pins (GPIO 34-39): Lack internal pull-up/pull-down resistors and cannot be configured as outputs. RTC GPIOs: Can wake the ESP32 from deep sleep and be controlled by the ULP co-processor.

ESP32 pinout diagram and explanation of all pins with ESP32 devkit and how to use these GPIO pins? Which pin to use with step by step guide

Jan 19, 2022 · In the ESP32 pinout, if you count the pins on an ESP-WROOM-32 bar module, you will see that it has a total of 38 pins. Among these pins, including power, GND, reset, NC pins, etc., only 33 are GPIO pins.

Nov 13, 2023 · 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.
