SPIDER Automation 1.54-Inch ST7789V TFT LCD Display Module | 240 × 240 IPS Screen with SPI Interface
Description
The SPIDER Automation 1.54-Inch ST7789V TFT LCD Display Module is a compact full-colour display solution for embedded electronic equipment, instrumentation and custom graphical user interfaces. It features a 240 × 240 pixel square display matrix with IPS panel technology and a 23.4 × 23.4mm active viewing area. The resolution provides 57,600 addressable pixels for rendering text, icons, numerical measurements, menus and graphical status information.
The module incorporates the ST7789V display controller IC and communicates through an SPI serial interface. This arrangement supports integration with compatible microcontrollers and embedded control boards using suitable display-driver firmware. The screen has a 22-pin connection and operates at a specified voltage of 2.8V. A white LED backlight illuminates the display panel, while the IPS architecture provides wide-angle viewing characteristics for equipment interfaces.
The specified operating temperature range is −10°C to 60°C, with a storage temperature range of −20°C to 70°C. Its compact square format and dedicated display controller make it suitable for custom PCB assemblies and embedded products requiring local graphical feedback within a limited installation area.
IPS TFT Display Technology & Active Viewing Area
The display uses Thin-Film Transistor (TFT) LCD technology with an In-Plane Switching (IPS) panel. IPS technology is designed to provide wider viewing angles than conventional narrow-viewing-angle LCD arrangements, helping maintain the visibility of displayed information when the screen is viewed from different positions.
The active display area measures 23.4 × 23.4mm, giving the screen a square viewing region. This geometry is useful for compact interface layouts in which graphical elements, numerical values and status indicators are arranged within a balanced display area.
- TFT LCD Architecture: Uses an active-matrix display structure for graphical image presentation.
- IPS Panel: Provides wide-angle viewing characteristics for embedded display applications.
- Square Active Area: Provides a 23.4 × 23.4mm usable viewing region.
- Full-Colour Display: Supports colour graphical output through the display controller and compatible host configuration.
- White LED Backlight: Provides illumination behind the LCD panel for viewing displayed content.
240 × 240 Resolution & Graphical Output
The ST7789V display module provides a 240 × 240 pixel resolution, with 240 pixels along each display axis. The resulting 57,600 addressable pixel positions allow compatible host software to render graphical interface elements, text, symbols, numerical readings and visual status information.
- Native Pixel Resolution: 240 × 240 pixels for square-format graphical output.
- Total Pixel Count: 57,600 addressable pixels, calculated from the specified horizontal and vertical resolution.
- Square Resolution Ratio: A 1:1 pixel matrix ratio supports balanced interface layouts.
- Text Rendering: Supports text and numerical information through compatible display libraries.
- Icon and Symbol Display: Allows host software to render graphical symbols, menus and status indicators.
- Measurement Visualisation: Can present sensor readings, operating values and other data generated by the connected system.
ST7789V Controller & SPI Communication
The module incorporates the ST7789V display controller IC, which manages display-control operations and the presentation of graphical data on the TFT panel. The controller works with the host system through the module’s SPI serial interface, allowing compatible embedded processors to communicate with the display using a serial data connection.
SPI (Serial Peripheral Interface) is commonly used for communication between microcontrollers and peripheral devices. In this display arrangement, the host system uses suitable firmware and an ST7789V-compatible display driver to initialise the screen, configure display parameters and transfer graphical content.
- ST7789V Display Driver: Provides the controller architecture for managing the TFT display.
- SPI Serial Communication: Enables communication between the display module and a compatible host processor.
- Microcontroller Integration: Supports embedded systems equipped with an appropriate SPI interface.
- Display Initialisation: Requires compatible firmware to configure the controller and initialise graphical output.
- Graphical Data Transfer: Allows compatible host software to update screen content through serial communication.
The SPI interface designation does not independently establish the supported clock frequency, logic-level tolerance, complete signal pinout or colour-data configuration. These parameters should be matched to the actual module documentation and host-board design.
22-Pin Connection & Electrical Integration
The display is supplied with a 22-pin connection arrangement for integration with a compatible host board. The specified 2.8V operating voltage is an important design requirement when selecting the power supply and planning the display interface circuitry.
- 22-Pin Connection: Provides the specified contact arrangement for connecting the display to compatible electronics.
- 2.8V Operating Voltage: Defines the stated operating-voltage requirement of the module.
- SPI Host Interface: Requires a compatible serial communication interface and display driver.
- PCB-Level Integration: Supports incorporation into custom embedded controller and interface boards.
- Signal Compatibility: Requires verification of pin assignments, logic levels and power connections before electrical integration.
Electrical integration note: The 2.8V operating specification should not be interpreted as confirmation that every interface signal is 3.3V- or 5V-tolerant. Verify the power and logic-level requirements before connecting the module to a host controller.
Operating & Storage Temperature Characteristics
The E1505A display module is specified for operation between −10°C and 60°C. Its storage temperature range extends from −20°C to 70°C. These temperature limits are relevant when selecting the module for electronic equipment installed in environments with changing ambient temperatures.

Connection & Operating Recommendations
- Verify the 2.8V Supply Requirement: Use a power arrangement that meets the module’s specified operating voltage. Do not connect it directly to a higher-voltage supply without confirming the required regulation circuitry.
- Check Host Logic Levels: Verify the SPI signal voltage compatibility between the display and the host processor before connection.
- Confirm the 22-Pin Pinout: Obtain the correct pin assignment and connector orientation before designing the PCB or connecting the display.
- Use an ST7789V-Compatible Driver: Configure the host firmware for the correct controller, 240 × 240 resolution and display initialisation sequence.
- Configure SPI Communication: Match the host communication settings to the display’s supported SPI configuration.
- Account for Backlight Power: Include the backlight’s electrical requirements in the power-budget design rather than assuming the panel’s operating voltage alone defines total system consumption.
- Respect Temperature Limits: Keep the operating environment within −10°C to 60°C and storage conditions within −20°C to 70°C.
- Allow Active-Area Clearance: Account for the 23.4 × 23.4mm active display region and the complete module outline when designing the enclosure and viewing aperture.
- Protect the Display Surface: Avoid pressure, scratching and bending forces during handling, mounting and enclosure assembly.
- Test Before Final Assembly: Verify power-up, display initialisation, SPI communication, backlight operation and graphical output before completing equipment integration.
