Getting started with Arduino

Arduino board definition​

To program your NULA DeepSleep ESP32-S3, use the official Espressif Arduino core for ESP32. This package already includes support for the Soldered NULA DeepSleep ESP32-S3, so you can select it directly from the board list after installation.

Espressif Arduino core for ESP32

Official Arduino core by Espressif, supporting ESP32, ESP32-C3, ESP32-S3, and ESP32-C6 boards including the Soldered NULA DeepSleep ESP32-S3.

Getting started with Arduino

A comprehensive beginner’s guide to setting up Arduino and uploading your first program.

Installing the ESP32 board package​

You can install the Espressif ESP32 boards directly from the Arduino Boards Manager:

  1. Open Arduino IDE
  2. Go to Tools → Board → Boards Manager
  3. In the search bar, type ESP32
  4. Find the entry ESP32 by Espressif Systems and click Install

Once installed, select your board from the menu:
Tools → Board → esp32 → Soldered NULA DeepSleep ESP32-S3

ℹ️
If the Soldered NULA DeepSleep ESP32-S3 does not appear in the list, you can alternatively select:
Tools → Board → esp32 → ESP32S3 Dev Module
Both options are compatible for uploading and testing sketches.

Example sketch​

Once your board is selected and connected via USB-C, try uploading this simple example to verify everything is working:

void setup() {
  Serial.begin(115200);
  Serial.println("Hello from NULA DeepSleep ESP32-S3!");
}

void loop() {
  delay(1000);
  Serial.println("Running...");
}
ℹ️
If uploading fails, double-check that the correct board and port are selected. The NULA DeepSleep ESP32-S3 uses native USB, so no external driver is required.
