1.3 Inch IPS LCD Display Module 240x240 RGB 65K Color SPI ST7789

Description Specifications Box Content Downloads More Info The 1.3" IPS TFT LCD Display Module is a compact, full-color screen driven by the ST7789 controller IC. Featuring a high-resolution 240x240 pixel IPS panel, it delivers stunning 65K RGB colors with a true full viewing angle — no color distortion regardless of direction. It communicates via a 4-line SPI interface requiring only a handful of GPIO pins, making it effortless to integrate with Arduino, STM32, ESP32, Raspberry Pi, and virtually any other microcontroller platform. Note: This module has no CS pin — it cannot share the SPI bus with other SPI devices simultaneously. Features: ST7789 Driver IC IPS panel — full viewing angle, no color distortion 65K RGB color display 4-line SPI interface — minimal GPIO required Input Voltage: 3.3V Resolution: 240 x 240 Pixels Built-in backlight control Compatible with Arduino, STM32, ESP32, Raspberry Pi, MSP430, 8051, PIC, AVR, ARM Applications: Wearable devices and smart watches Embedded systems and IoT projects Handheld instruments and meters Industrial and security equipment Mini weather stations and clocks Smart home displays Pin Definition: Pin Name Description 1 GND Power ground 2 VCC Power supply positive (3.3V) 3 SCL SPI bus clock signal 4 SDA SPI bus write data signal 5 RES Reset control signal (active low) 6 DC Register/data selection (Low: register, High: data) 7 BLK Backlight control (High: on; connect to 3.3V if control not needed) Display Type IPS TFT LCD Driver IC ST7789 Resolution 240 x 240 Pixels Display Color RGB 65K Colors Screen Size 1.3 inch Active Area (AA) 23.40 x 23.40 mm PCB Size 39.22 x 27.78 mm Interface 4-line SPI Input Voltage 3.3V Luminance 490 cd/m² LED Current 32 mA Power Consumption 0.195W Viewing Angle Full Angle (IPS) Operating Temperature -30°C to +80°C Storage Temperature -30°C to +80°C Product Weight 9 grams 1.3" IPS TFT LCD Display Module (ST7789) Connection Please refer to the pin definition table in the Description tab for wiring details. Connect VCC and GND to 3.3V and ground respectively. SCL, SDA, RES, and DC connect to your microcontroller's SPI and GPIO pins. This module has no CS pin — it cannot share the SPI bus with other devices. BLK connects to 3.3V to keep the backlight on permanently, or to a GPIO/PWM pin for software brightness control.
