Full-Colour TFT Display

The Waveshare 2.8 Inch LCD Module features a 240 × 320 pixel TFT panel capable of displaying up to 262K colours.

The screen is suitable for displaying graphical user interfaces, sensor readings, icons, menus, images and system information.

Its compact design makes it particularly useful for projects where a larger touchscreen is required without taking up excessive space.

Responsive 5-Point Capacitive Touch

The integrated CST328 capacitive touch controller supports up to five simultaneous touch points, allowing developers to create interactive applications with touch-based controls.

Capacitive touch technology offers several advantages over conventional resistive touchscreens, including:

• Fast and responsive touch detection

• Support for multi-touch interaction

• High screen light transmission

• Durable touch operation

• Smooth interaction with on-screen menus and controls

This makes the display suitable for smart home controllers, embedded control panels, interactive instruments and portable electronics.

SPI Display and I2C Touch Communication

The module uses two communication interfaces:

4-Wire SPI Interface

The ST7789 display driver communicates with the host microcontroller using SPI, allowing efficient transfer of graphical display data.

I2C Touch Interface

The CST328 capacitive touch controller communicates through I2C, allowing the host device to read touch input and coordinates.

These interfaces minimise the GPIO requirements compared with parallel display connections.

Pin Connections

• VCC: Power supply input (3.3V / 5V)

• GND: Ground

• MISO: SPI MISO

• MOSI: SPI MOSI

• SCLK: SPI clock

• LCD_CS: LCD chip select (active low)

• LCD_DC: LCD data/command selection
