Debugging on ESP32‐S3

• ESP32-S3 has a built-in JTAG circuitry and can be debugged without any additional chip or adapter
• PlatformIO uses the esp-builtin on-board debug tool by default when the Espressif ESP32-S3-DevKitC-1-N8 (esp32-s3-devkitc-1) board is selected. See here for a list of Espressif boards where PlatformIO can use on-board debug tool.
