1.69 inch TFT LCD screen SPI ST7789 240×280 rounded corner Bare Module

Description

Overview

Compact 1.69-inch full-color TFT LCD display module featuring a 240 × 280 pixel resolution and ST7789V display driver.
The display uses an SPI interface, requiring only a small number of MCU pins for communication.
Its rounded-corner design makes it suitable for compact and modern embedded products, handheld devices, control panels, and wearable-style applications.
This version is supplied as a bare display module with an 12-pin Soldering connection. The supplied specification indicates a 2.8–3.3 V operating voltage and -20°C to +70°C operating temperature.

Key Features

• 1.69-inch color TFT LCD
• 240 × 280 RGB resolution
• ST7789V display driver
• SPI interface
• Rounded-corner display design
• 12pin Soldering connection
• Compact and thin display construction
• 2.8–3.3 V operating voltage

Technical Specifications

The supplied specifications match common 1.69-inch 240×280 ST7789 displays, which use an SPI interface and have an approximately 27.97 × 32.63 mm active display area.

Interface

The display uses an SPI interface for communication with the host microcontroller. The exact signal assignment of the 12-pin FPC should be verified against the specific panel revision before PCB design or assembly, as different 1.69-inch ST7789 panels can use different FPC pin assignments.

Typical SPI signals include:

• VCC
• GND
• SCK / CLK
• MOSI / SDA
• CS
• DC / RS
• RESET
• Backlight

Power & Programming

The display requires a 2.8–3.3 V supply according to the supplied product specification.

It can be interfaced with microcontrollers such as:

• ESP32 / ESP32-C series
• STM32
• Arduino-compatible MCUs
• RP2040
• Other 3.3 V embedded controllers

The ST7789 family is widely supported by embedded graphics libraries, including Arduino-compatible libraries.

Important: This is a bare display module and does not include an onboard 5 V regulator or 5 V logic-level conversion unless specifically stated for the particular version.

Applications

• Embedded user interfaces
• Handheld devices
• IoT products
• Smart devices
• Wearable electronics
• Control panels
• Instrument displays
• ESP32 projects
• STM32 projects
• Arduino projects
• Portable electronic equipment
• Custom product development

What’s Included

• 1 × 1.69-inch 240×280 TFT LCD ST7789V Bare Display Module

Notes

• Bare module: No development board, controller board, FPC cable, or external driver circuitry is included unless separately specified.
• Verify the 12-pin FPC pinout and cable orientation before connecting the display to a PCB.
• The display should be operated within the specified 2.8–3.3 V supply range.
• Although ST7789-based displays are commonly supported by Arduino and other MCU libraries, the exact initialization sequence may vary between panel revisions.
• The rounded corners are part of the physical display design; software should use the specified 240 × 280 pixel coordinate system.
