1.3 inch TFT 240x240 dot matrix ST7789 driver SPI interface display module

1.3 Inch 240x240 RGB TFT IPS LCD Display Module (7-pin, ST7789)

This is a 1.3-inch full-color IPS LCD display module with a 240x240 pixel resolution and an ST7789 display controller. It connects over a 4-line SPI interface and operates from a 3.3V supply. The IPS panel provides a wide viewing angle and a pixel density of approximately 260 PPI, allowing detailed graphics and text in a compact form factor.

Specifications

Features

• Full-color RGB IPS display with wide viewing angle
• 240x240 high-resolution panel
• ST7789 controller with 4-line SPI interface
• 7-pin header for breadboard or connector mounting
• Backlight control via BLK pin
• No onboard 3.3V regulator; must be powered from 3.3V

Pin Connections (7-pin header)

• GND – system ground (common with MCU)
• VCC – 3.3V supply
• SCL – SPI clock
• SDA – SPI MOSI (data)
• RES – reset for the ST7789 controller (normally HIGH, pull LOW to reset)
• DC – data/command select (LOW = command, HIGH = data)
• BLK – backlight control (leave unconnected for always-on; pull LOW to turn off)

Notes

When used with a 5V microcontroller, logic level shifters should be included on the data lines to prevent damage. The module is mounted on a PCB for support; apply pressure to the header pins rather than the glass when inserting into a breadboard.
