4. Setup and Installation
4.1 Module Insertion
Carefully insert the ESP32-S3-WROOM-1 module into the burning fixture development board. Ensure all pins are correctly aligned with the sockets on the board to prevent damage.
4.2 Power Connection
Connect a stable DC 3.3V power supply to the development board. Verify the power connections before proceeding.
4.3 Serial Port Connection
To enable software automatic download mode, connect the EN (Enable) and GPIO (General Purpose Input/Output) pins of the module to the DTR (Data Terminal Ready) and RTS (Request To Send) pins of your serial port chip, respectively. This configuration allows your programming software to control the module's boot mode.
5. Operating Instructions
5.1 Module Reset (RST Pin)
The Wi-Fi module's RST (Reset) pin is active at a low logic level. Pulling this pin low will reset the module.
5.2 UART Communication
For serial communication with an external Microcontroller Unit (MCU):
- Connect the RXD (Receive Data) pin of the Wi-Fi module to the TXD (Transmit Data) pin of the external MCU.
- Connect the TXD (Transmit Data) pin of the Wi-Fi module to the RXD (Receive Data) pin of the external MCU.
5.3 Boot Modes
The module supports two primary boot modes:
- FLASH Download Mode: To enter this mode, ensure the I00 pin is at a low logic level. Then, reset and power on the module. This mode is used for flashing new firmware onto the module.
- Normal Working Mode: To enter this mode, ensure the I00 pin is at a high logic level. Then, reset and power on the module. This mode is for running the loaded application firmware.
6. Pin Definitions
Understanding the pinout of the ESP32-S3-WROOM-1 module is crucial for proper integration and development. Refer to the diagram below for detailed pin definitions.
7. Module Dimensions

8. Wiring Diagram
For advanced users and custom integrations, the schematic diagram of the development board provides insight into its internal circuitry and connections.
9. User Tips
- Always double-check pin connections before applying power to avoid damaging the module or development board.
- Ensure your development environment (e.g., Arduino IDE, ESP-IDF) is correctly configured for the ESP32-S3 series.
- When troubleshooting, verify the power supply voltage is stable at 3.3V.
- For reliable programming, use a high-quality USB cable.
10. Troubleshooting
- Module not detected: Check USB cable connection, driver installation for the serial chip, and ensure the module is correctly seated in the fixture.
- Failed to flash firmware: Verify the module is in FLASH download mode (I00 low on reset/power-on). Check your programming software settings and baud rate.
- Unstable operation: Ensure a stable 3.3V power supply. Check for loose connections or short circuits.
- Wi-Fi/Bluetooth issues: Confirm antenna connection (if external) and proper firmware configuration for wireless functionalities.
11. Maintenance
- Keep the module and development board clean and free from dust and moisture.
- Store in an anti-static environment when not in use.
- Avoid exposing the components to extreme temperatures or direct sunlight.
- Do not attempt to repair internal components unless you are a qualified technician.
12. Warranty and Support
