Getting Started with ESP32-S3 Dev Board: Setup & Guide

The article provides a step-by-step guide for first-time users of the ESP32 development board, detailing how to configure Arduino IDE, select the appropriate board settings, and execute a simple LED blinking program. It covers essential configurations such as USB CDC settings and partition schemes, ensuring a smooth setup process for beginners.

Tutorial - First Time Use

Arduino IDE Configuration

When you use the ESP32 for the first time, you need to know the following steps:

Add the ESP32 development board in Arduino IDE (How to add the ESP32 board to Arduino IDE?)
Select the development board and serial port
Burn the program

Select Development Board

Click Tools->Board, select "DFRobot LoRaWAN ESP32-S3".
The development board needs to be set before burning the code:

USB CDC On Boot:
Enabled: Print serial port data through the USB interface
Disabled: Print serial port data through TX and RX
Partition Scheme: Disk partitioning scheme. Please select the appropriate storage space according to the Flash of the development board.
Port: Development board port (Just make sure the COM number is correct, which has nothing to do with the subsequent chip model.)

LED Blinking

Copy the code into the window and click "Upload" to upload the code.

int led = 21;
void setup() {
  pinMode(led,OUTPUT);
}

void loop() {
  digitalWrite(led,HIGH);
  delay(1000);
  digitalWrite(led,LOW);
  delay(1000);
}

LED Blinking

Wait for the burning to complete, and you can see the on-board LED light start to flash.
- If the LED light does not flash, reset the development board.
- If the burning fails, please check Frequently Asked Questions.
