I’ll set up an official USB‑C ESP32‑S3 DevKit build matching your sketch with I2S audio, 2× shift registers, and an SPI ILI9488 TFT.
Plan
  1. Add parts: ESP32‑S3‑DEVKITC‑1, MAX98357A, 2× 74HC595, ILI9488, Tactile Switch.
  2. Wire per your defines: I2S on GPIO4/5/6, SR on GPIO15/16/17, button on GPIO21.
  3. Confirm TFT_eSPI pin map, then wire SPI/control pins.
  4. Label nets and review.
Before I run it:
  • Confirm the dev board: keep ESP32‑S3‑DEVKITC‑1 USB‑C?
  • Share your TFT_eSPI pin assignments for the ILI9488 (MOSI/SCK/CS/DC/RST/BL).
  • Power for MAX98357A: 5 V from USB or 3.3 V?
Click Start on the plan bar and I’ll execute this setup.
