Pinout

The ESP32-S3 is a powerful esp32 SOC

ESP-IDF

Let me explain how to flash the ESP32-S3 via USB-C port on your ESP32-S3-WROOM-1 DevKit:

1. Normal Mode Flashing:

Copy

- Connect the board to your computer via USB-C cable - No need to hold any buttons initially - The board should be automatically detected

2. If Normal Mode doesn’t work, use Download Mode:

Copy

- Hold down the BOOT button (GPIO0) - While holding BOOT, press and release the RESET button - Release the BOOT button - The board should now be in download mode

3. For idf.py commands:

bash

Copy

# First, find your port idf.py -p PORT flash # On Windows might be COM3, on Linux /dev/ttyACM0 or similar # Example: idf.py -p COM3 flash # Windows idf.py -p /dev/ttyACM0 flash # Linux

Key points:

• The ESP32-S3 has built-in USB-Serial support, so no external USB-UART bridge is needed
• Make sure you have proper USB drivers installed:
  • Windows: Usually installs automatically
  • Linux: Usually works out of the box
  • macOS: Usually works out of the box
• If the port isn’t detected, try:
  1. Different USB cable (some cables are power-only)
  2. Different USB port on your computer
  3. Reinstalling USB drivers
