This 2.8-inch TFT touch screen module is an ideal display for projects that require high-resolution, vibrant visuals combined with touch functionality. With a resolution of 240x320 pixels and individual RGB pixel control, it delivers sharp and colorful graphics far superior to standard black-and-white displays. The resistive touchscreen adds an interactive dimension, allowing for precise user inputs.

Features:

1. High-Resolution Display:

   • 240x320 pixel resolution with 65K colors for stunning visuals.

2. Resistive Touchscreen:

   • Detects touch inputs across the screen for interactive applications.

3. Versatile Operating Modes:

   • 8-bit Parallel Mode: High-speed data transfer using 8 data lines and 4-5 control lines.
   • SPI Mode: Minimal pin usage with only 5 connections (slower than 8-bit mode).

4. Built-in Controller with RAM:

   • Offloads graphical processing from the microcontroller, improving performance.

5. MicroSD Card Slot:

   • Enables image and asset storage, ideal for applications needing dynamic graphics.

6. Voltage Compatibility:

   • Works with 3.3V and 5V logic, thanks to built-in level shifters, ensuring compatibility with most microcontrollers.

Wiring Options:

8-bit Parallel Mode:

Requires 8 digital lines for data (D0–D7) and 4-5 digital control lines (CS, RS, WR, RD, RESET). Offers the fastest performance but uses more pins.

SPI Mode:

Requires fewer connections (5 total), including MOSI, MISO, SCK, CS, and D/C. Easier to use in pin-limited systems but slower than 8-bit mode.

Touchscreen:

• Requires 4 connections (2 analog for X/Y axis, 2 digital for touch control).

MicroSD Card:

• Controlled via SPI pins, sharing the SPI bus with the display.
