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.</p> <p>That distinction determines the wiring. The devices may share SPI clock and data lines, while each peripheral keeps its own chip-select signal.</p>
