Overview
Introduction
The ESP32-S3-DEV-KIT-N8R8 is a compact microcontroller development board with multiple interfaces.
In terms of hardware, the ESP32-S3-WROOM-1-N8R8 module is equipped with an Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240MHz, 512KB SRAM (TCM) and 8MB PSRAM, and a CH343 serial port and CH334 USB HUB dual chip on board, allowing simultaneous USB and UART use and development via a USB-C interface. The pin is compatible with the ESP32-S3-DevKitC-1 development board, which is compatible with the expansion of a variety of peripherals, making it more convenient to use.
In terms of software, development environments such as ESP-IDF, Arduino, and MicroPython can be selected for development, making it easy to get started quickly and apply them to products.

Development Environment Configuration
- The following development system is Windows by default.
ESP-IDF
- It is recommended to develop with the VSC plug-in.
Develop with VSCode
Install VSCode
- 1. Open the download page of the official VSCode website, and select the corresponding system and system bit to download.
- 2. After running the installation package, the rest can be installed by default, but here for the subsequent experience, it is recommended to check boxes 1, 2, and 3.
- After the first two items are enabled, you can open VSCode directly by right-clicking files or directories, which can improve the subsequent user experience.
- After the third item is enabled, you can select VSCode directly when you choose how to open it.
Install Espressif IDF Plug-in
- Note: The latest version of the current plug-in is V1.6.0, for a consistent experience, users can choose the same version as us.
- 1. Open VSCode and use the shortcut key Shift + Ctrl + X to enter the plugin manager.
- 2. In the search bar, type Espressif IDF, select the corresponding plug-in, and click install.
- 3. Press F1 to enter:
esp-idf: configure esp-idf extension
- 4. Choose express (This tutorial is for users who install it for the first time, so only the first general installation tutorial is covered.)
- 5. Open and display this screen.
- 6. Choose a server to download.
- 7. Select the ESP-IDF version you want now, we choose the latest V5.0.1 (note that ESP-IDF started to support ESP32-S3 only after V4.4).
- 8. The following two are the ESP-IDF directory installation address and the ESP-IDF required tools installation address respectively.
- Note: If you have installed ESP-IDF before, or if it has failed, please make sure to delete the file completely or create a new path.
- 9. Once the configuration is finished, click "install" to download.
- 10. Enter the download page, and it will automatically install the corresponding tools and environment, just wait a moment.
- 11. After the installation is completed, it will enter the following screen, indicating that the installation is finished.
Official Demo Usage
- Click here to view more details provided by the official ESP.
Creating a Demo
- 1. Using the shortcut F1, type:
esp-idf:show examples projects
- 2. Choose your current IDF version:
- 3. Take "Hello World" as an example:
- 4. ① Choose the corresponding demo.
- 5. ② The readme file will explain which chip the demo is suitable for (the following section will introduce how to use the demo and its file structure, which is omitted here).
- 6. ③ Click to create the demo.
- 7. Choose the path to place the demo and ensure that there is no folder with the same name as the demo.
Modify COM Port
- 1. The corresponding COM port is displayed here, click on it to modify.
- 2. We check the device manager COM port, and select COM5, please select according to your corresponding COM port：
- 3. Choose the project and demo.
- 4. Then the COM port is modified.
Modify the Driver
- 1. Here shows the driver used, click here to modify the corresponding driver:
- 2. Choose the project or demo:
- 3. Wait for a few seconds after clicking.
- 4. Choose the driver we need, that is, the main chip ESP32S3.
- 5. Choose the openocd path, we can just choose one as it doesn't matter.
The Rest of the Status Bar Introduction
- ① SDK configuration editor: many functions and configurations of ESP-IDF can be modified within it.
- ② Clean up everything and delete all compiled files.
- ③ Compile.
- ④ Current download method, default is UART.
- ⑤ Program the current firmware, please do it after compiling.
- ⑥ Open the serial monitor to view serial information.
- ⑦ Combined button for compiling, programming, and opening the serial monitor (most commonly used during debugging).
Compile, Program, and Serial Port Monitoring
- 1. Click on the Compile, Program, and Open Serial Monitor buttons we described earlier.
- 2. It may take a long time to compile, especially for the first time.
- During this process, ESP-IDF may take up a lot of CPU resources and therefore may cause system lag.
- 3. If it fails to download, you can hold the boot button to power on and then release the button, and then program the download.
- 4. After successful download, it will automatically enter the serial monitor, and you can see the corresponding information output from the chip and prompt to reboot after 10s.

FAQ
Answer:
Check if the power supply voltage of the USB port is less than 5V. Generally, the power supply voltage of the USB port is above 4.9V, and both USB ports of the module can be used normally. If it is lower than 4.9V, there may be insufficient power supply and USB port disconnection. In this case, it is necessary to replace the USB port with sufficient voltage.
Answer:
Long press the BOOT button, then press RESET at the same time, release RESET and then release the BOOT button. At this time, the module can enter the download mode, which can solve most of the problems that cannot be downloaded.
