Driving an ILI9341 SPI Display and Touch Controller from ESP32-S3

A 2.4-inch 240 × 320 TFT module built around the ILI9341 is a practical match for an ESP32-S3 because the display controller accepts a serial SPI interface. The module is not necessarily one device: a typical board can contain the ILI9341 for pixels, a separate resistive-touch controller, and sometimes a microSD socket. That distinction determines the wiring. The devices may share SPI clock and data lines, while each peripheral keeps its own chip-select signal.
