3V3 pin and connect GND to ground.esptool.py) for firmware flashing and updates.The ESP32-S3-N16R8 can be programmed using the Arduino IDE. Below is an example of connecting the ESP32-S3-N16R8 to a Wi-Fi network and toggling an LED:
#include <WiFi.h> // Include the Wi-Fi library
// Replace with your network credentials
const char* ssid = "Your_SSID";
const char* password = "Your_PASSWORD";
const int ledPin = 2; // GPIO2 is connected to an LED
void setup() {
pinMode(ledPin, OUTPUT); // Set GPIO2 as an output
Serial.begin(115200); // Start serial communication
// Connect to Wi-Fi
Serial.print("Connecting to Wi-Fi");
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("\nWi-Fi connected!");
Serial.print("IP Address: ");
Serial.println(WiFi.localIP());
}
void loop() {
digitalWrite(ledPin, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(ledPin, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
