The other problem of this board is the pinout limitations. Make sure, if you are new with the ESP32, that you watch this YouTube video. On startup some of the GPIOs have to be in specific states in order to the ESP32 to boot normally. But this is not a big problem once you get...

smart pinout ... direct connect I2C/TWI boards, RTC, EEPROM, Led strips, I2C LCD - no shield required !!! partially breadboard compatible, you can insert 1 row, if you need more breadboard friendly board - Check out my other items! board can be covered by transparent or white heat shri...
Here’s a simple ESP8266 pinout guide: VCC: Connect to 3.3V power supply GND: Connect to ground of the UART or Arduino TX: Connect to RX of the UART or Arduino RX: Connect to TX of the UART or Arduino (use a voltage divider to step down from 5V to 3.3V if using Arduino)...

Note: You can use any pin you want, as long as it can act as an output. All pins that can act as outputs can be used as PWM pins. For more information about the ESP32 GPIOs, read: ESP32 Pinout Reference: Which GPIO pins should you use?
In this example, we’re using GPIO 5 and GPIO 18. But you can use any other suitable GPIOs—read ESP32 Pinout Reference: Which GPIO pins should you use?The SOUND_SPEED variable saves the velocity of sound in the air at 20ºC. We’re using the value in cm/uS....
The common 8-bit "Mcufriend" shields are supported for the STM Nucleo 64/144 boards and ESP32 UNO style board. The STM32 "Blue/Black Pill" boards can also be used with 8-bit parallel displays. The ESP32 board I have been using for testing has the following pinout: ...
The STM32 "Blue/Black Pill" boards can also be used with 8-bit parallel displays. The ESP32 board I have been using for testing has the following pinout: UNO style boards with a Wemos R32(ESP32) label are also available at low cost with the same pinout. Unfortunately the typical UNO/...
