ESP32-S3-DevBoard

A custom-built development board using the ESP32-S3 chip

PlatformIO Setup

NOTE: This process only needs to be performed once for each development board

1. Download the Zadig driver installation program here: https://zadig.akeo.ie

2. Open Zadig, then click Options -> List All Devices

3. Select USB JTAG/serial debug unit (Interface 0) and change the driver to USB Serial (CDC)

4. Click "Upgrade/Downgrade Driver" (please note, this process may take a few minutes)

5. Select USB JTAG/serial debug unit (Interface 2) and change the driver to libusbK

6. Click "Upgrade/Downgrade Driver" (please note, this process may take a few minutes)

7. In PlatformIO, configure the platformio.ini file as follows:

    [env:esp32-s3-devboard]
   
    platform = https://github.com/platformio/platform-espressif32.git
    board = esp32-s3-devkitc-1
    framework = arduino
   
    upload_speed = 2000000
    monitor_speed = 115200
   
    debug_tool = esp-builtin
    debug_init_break = break setup
    build_type = debug
   
    ; enables CDC mode (activates USB-to-Serial)
    build_flags = -DARDUINO_USB_CDC_ON_BOOT=1
