WT9932S3-NANO Beginner's Guide

Windows/MAC Arduino Environment Setup

For related content, please refer to the official documentation:
https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html#installing-using-arduino-ide

1. Visit the Arduino official website and download the IDE development tool:
   https://www.arduino.cc/en/software/

2. Install the latest IDE. As of 2025.11.01, the latest version is 2.3.6
   

3. Install the ESP32 board support package
   [Pay attention to the network environment during installation. If the search or installation fails, consider using a domestic mirror.]
   Before installing the ESP32 boards, you need to add the ESP32 Board Manager URL in
   IDE → Preferences → Settings:
   Open Arduino IDE → “File > Preferences”, and enter the official JSON link in
   “Additional Boards Manager URLs”
   ( https://espressif.github.io/arduino-esp32/package_esp32_index.json
   or China mirror: https://jihulab.com/esp-mirror/espressif/arduino-esp32/-/raw/gh-pages/package_esp32_index_cn.json )

   Since the ESP32 toolchain is relatively large, the download may take some time.
   Make sure each URL is on a separate line, with no extra spaces or characters.

   

   

4. Verify whether the installation is successful
   a. Check whether the corresponding development board can be found under
   IDE → Tools → Board
   
   b. After connecting the development board, check whether the corresponding serial port appears
   【If it does, the installation is successful】

Environment Verification – Blink LED Example

Arduino IDE → File → Examples → 01 Basics → Blink

/*  https://docs.arduino.cc/built-in-examples/basics/Blink/
*/

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}

Compile and upload directly.
If it compiles successfully, uploads to the Arduino board correctly, and the LED blinks normally, the verification is passed.

A normal upload and flashing log is shown below:
