3.5 Inch TFT LCD Module 320x480 ST7796 40pin
3.5 Inch TFT LCD Module 320x480 Dots ST7796 40pin Serial Interface Touch Optional
Key Features of a 3.5-Inch TFT Display:
-
Color Depth:
-
These displays support 16.7 million colors (24-bit color), meaning they can produce vibrant and accurate images and graphics.
-
-
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).
-
-
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.

Connecting a 3.5-Inch TFT Display to Raspberry Pi:
To connect a 3.5-inch TFT display to a Raspberry Pi, you’ll typically use the GPIO pins or SPI interface, and you may need to install drivers for the screen.
Steps for Setting Up on Raspberry Pi:
-
Connect the display to the Raspberry Pi via the GPIO pins or SPI interface, following the display's datasheet for correct pinout.
-
Install necessary libraries. You might need to install Python libraries like Pillow (for image handling) and RPi.GPIO (for GPIO control).
-
Install the drivers. Depending on the display controller, you may need to install specific drivers or use pre-configured Raspbian images that support these displays.
-
Write your code to interact with the display, whether you’re showing static images, text, or implementing an interactive user interface.
