SPIDER Automation GMT177-07 1.77-Inch TFT LCD Display Module | 128 × 160 Resolution with ST7735S SPI Interface
The GMT177-07 1.77-Inch TFT LCD Display Module is a compact colour display designed for embedded electronic equipment, microcontroller-based systems and graphical user-interface applications. It features a 128 × 160 pixel resolution and an ST7735S display driver IC, providing a controlled display interface for presenting text, icons, menus, measurement readings and graphical information.
The module communicates through an SPI serial interface and uses a 14-pin connection for integration with compatible host electronics. Measuring 42 × 32 × 3mm and weighing approximately 5g, its compact construction is suitable for electronic assemblies where display size, installation space and overall component weight are important design considerations. The specified operating temperature range is -20°C to +70°C, with a storage temperature range of -30°C to +80°C.
Product Overview & Display Design
The GMT177-07 combines a 1.77-inch TFT display panel with the ST7735S display controller to provide graphical output through an SPI communication interface. Its 128 × 160 resolution provides a total of 20,480 pixels, allowing embedded systems to present structured visual information within a compact display area.
The SPI interface provides a serial communication arrangement between the display module and a compatible host controller. This allows the display to be incorporated into electronic products where a graphical interface is required without using a parallel display data connection. The 14-pin interface forms the module’s electrical connection point, with the host system requiring a compatible connector and signal configuration.

Display Resolution & Graphical Output
The display provides a 128-pixel horizontal by 160-pixel vertical resolution. This pixel matrix supports the presentation of compact graphical interfaces, status indicators, numerical values and text-based information. The display orientation and graphical layout can be configured in the host software according to the application’s interface requirements.
The ST7735S controller provides the display-control functionality, while the host processor communicates with the module through SPI. Software integration therefore requires a compatible display driver and appropriate initialization and configuration settings for the module.
SPI Interface & Embedded-System Integration
The GMT177-07 uses an SPI communication interface for transferring display-control and image data from a compatible host system. SPI is commonly used in embedded electronics where serial communication is preferred for connecting display peripherals to microcontrollers and other processing devices.
The 14-pin connection provides the physical interface for the module. Before integration, the host-side connector and electrical signal assignments must be matched to the display’s actual pin configuration. A compatible ST7735S software driver and the correct display initialization settings are also required for operation.
