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.

For a step-by-step guide on installing Arduino, connecting your board, and uploading your first sketch, see this section of our docs:

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.

Install CH340 driver​

The CH340 is an onboard chip that enables serial communication over USB. Without the driver, the board may not show up as a serial port on your computer.

ℹ️
Linux users can skip this step because the CH340 driver is already installed.

Windows​

If the driver is not installed, download it from this link. Start the installation and follow the instructions.

Mac​

On macOS, the CH340 driver needs to be installed manually. Download it from the official WCH website, open the .dmg file, and follow the installation instructions:

ℹ️
After installing, macOS may ask you to allow the driver in System Settings → Privacy & Security. Restart your Mac if the board is not detected after installation.

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, and make sure the CH340 driver is installed (see the section above).
