Key Features of a 3.5-Inch TFT Display:

1. Color Depth:

   • These displays support 16.7 million colors (24-bit color), meaning they can produce vibrant and accurate images and graphics.

2. Touchscreen (Optional):

   • Many 3.5-inch TFT displays come with a resistive or capacitive touchscreen layer, enabling user interaction via touch. Resistive touch is pressure-sensitive and works with any object (including a finger, stylus, or gloves), whereas capacitive touch is more sensitive and supports multi-touch gestures but usually requires conductive input (finger).

3. Interface:

   • SPI (Serial Peripheral Interface): Most 3.5-inch TFT displays use SPI for communication with microcontrollers or single-board computers like Arduino and Raspberry Pi. SPI uses fewer pins than parallel communication, making it more compact and easier to connect.

   • Parallel Interface: Some larger TFT displays use parallel communication for faster data transfer, though they require more I/O pins.
