2.4 Inch LCD Display 240x320, SPI Interface, ILI9341 UART

A compact 2.4 inch LCD display for embedded, IoT and industrial control interfaces

This 2.4 inch LCD display is a 240x320 TFT module with 4-wire SPI interface, ILI9341 driver and UART support, designed for embedded systems, IoT devices and compact industrial control panels. With 3.3V/5V operation, wide temperature range and optional capacitive touch, this display can be configured as a complete touch panel display with custom cover lens and interface to match different product requirements.

Why this 2.4 inch LCD display matters

In embedded and IoT devices, screens must be small, low-power and easy to integrate while still providing clear text and simple graphics. The 2.4 inch LCD display combines moderate resolution, common driver IC and simple SPI interface in a compact outline.

• 240x320 resolution on a 2.4 inch diagonal provides clear menus, status lines and basic UI elements.
• ILI9341 driver and 4-wire SPI interface are widely supported by MCU platforms and open-source libraries.
• 3.3V/5V operation simplifies power design in battery-powered and low-cost embedded projects.
• Optional capacitive touch allows the module to be used as a compact touch panel display.

How the SPI interface and ILI9341 driver work

The ILI9341 is a popular single-chip driver for 240x320 TFT panels. It supports 4-wire SPI, 8-bit MCU and other interfaces, making it suitable for a wide range of microcontroller-based designs.

• 4-wire SPI mode reduces signal lines while maintaining good update performance for text and simple graphics.
• UART support enables serial communication with host MCUs that prefer command-based control.
• Integrated driver IC reduces external components and simplifies PCB layout for compact devices.

What to check before buying a 2.4 inch LCD module

When selecting a 2.4 inch display for a project, the key parameters are resolution, interface, driver IC, mechanical fit and touch requirements.

• Confirm the available installation space against the module outline (77.18 × 42.72 mm) and display area (36.72 × 48.96 mm).
• Match the 4-wire SPI / UART interface and voltage (3.3V/5V) with your mainboard.
• Decide if you need a bare module or a solution with capacitive touch panel and cover lens already bonded.
• Check the operating temperature range (-20°C ~ +70°C) against your target application environment.
