Introduction of how to use
To start using this board and programming it from the PC or Laptop you must install its driver, in this case the board incorporates the CP2102 chip which is responsible for programming and establishing USB-Serial communication.
In the following link you can download the CP210x universal controller which includes the CP2102 version that the board needs:
CP210x Universal Controller
Note
Install the driver according to the operating system of your PC or Laptop.
If you have installed it previously, do not install the driver.
Once the driver is installed, you can connect the board to your PC.
To verify that the driver was installed correctly and a COM port was assigned to the board, follow these steps:
Open “Device Manager”
Connect the board to the PC
Click on Ports (COM, LPT)
You should recognize the plate as shown in the following image:

How to program ESP32 ?
Once the controller is installed, you can program it in different programming environments, you can choose:
Arduino IDE (in C++ language),
Esp-idf (Espressif IoT Development Framework) developed by the chip manufacturer,
Simba Embedded Programming Platform (in Python language)
MicroPython
Javascript (Espruino, Duktape, Mongoose JS)
And others…
It is widely used with Arduino IDE since it has a wide variety of examples, information and other resources that will help you start using this board.
To use with Arduino IDE you must perform the following steps:
Open Arduino IDE.
If you have not installed it, download it directly from the Arduino page , install the executable version, not install the portable version.
Copy the following URL: https://dl.espressif.com/dl/package_esp32_index.json
Go to the Arduino tab called “File”.
Click on “Preferences”.
Go to the Additional Card URL Manager:
In the box paste the URL. If there is another URL, place a comma at the end, give a space and paste the URL.
Click Ok.
Go to the Arduino tab called “Tools”
Click on “Plate:”   and then “Card Manager…”
A window will appear, look for the “esp32 by Espressif Systems” boards and install them.
To check the installation of ESP32 cards in Arduino IDE and upload codes to the board, do the following:
Go to the Arduino tab called “Tools”
Click on “Plate:”
Select ESP32 Arduino and search for the board “DOIT ESP32 DEVKIT V1”
You can also choose the boards: NodeMCU-32S ,  Adafruit ESP32 Feather or ESP32 Dev Module
Then connect the board to the PC.
Go to “Tools” again , select the “COM” port that the PC assigned to the board and verify that Flash Mode is set to DIO.
To check that everything went well, I recommend doing the “Hello world in ESP32” which consists of ordering a Blink code, which only turns an LED on the ESP32 on and off.

Note
If the program does not load directly to the board you will have to put the board in programming mode before loading the code.
To put it in programming mode, do the following
Press the “BOOT” button when the code is being uploaded Since the loading process begins, stop pressing the BOOT button.
You will have to do this process every time you upload a new sketch to the ESP32.
