1.3 Inch 240×240 RGB TFT IPS LCD Display Module 7pin ST7789 Chip

1.3 Inch 240×240 RGB TFT IPS LCD Display Module 7pin ST7789 Chip is a low-cost but powerful TFT display that makes your project look awesome! The display has 240 x 240 pixels resolution, and its size is only 1.3inch. This allows you to display a high-quality picture, to make your project really cool.

These full color displays can pack a lot of information into a small 1.3″ form factor with 260PPI (Pixels Per Inch). When you find these modules for sale, they are often mistakenly identified as an OLED display but they are in fact IPS LCD which has a similar wide viewing angle to OLED.

The module operates at 3.3V, so if using with a 5V MCU, be sure to include logic level shifters on the data lines to prevent possible damage.  The circuitry on the back of the module is just a transistor and a few resistors and capacitor to provide backlight control.  The module does not have a 3.3V regulator on it and so must be powered from 3.3V.

These modules are breadboard friendly with a 7-pin header on the back that can be inserted into a solderless breadboard or a 7-pin female connector can be used to connect to it if the display is to be mounted.  The display is mounted on a PCB which helps provide support, but be sure to press on the header pins when applying pressure to insert them into a breadboard and not press on the glass to avoid possible damage.

Display Connections

Connection to the display is via a 7-pin header.

• GND – Connect to system ground.  This ground needs to be in common with the MCU.
• VCC –  Connect to 3.3V.  This can come from the MCU or  separate power supply.
• SCL –  Connects to SPI SCL (Clock)
• SDA – Connect to SPI MOSI (Data)
• RES – Reset for the ST7789 LCD controller.  Normally HIGH, pull LOW to reset
• DC –   Data / Command.  Determines type type of data being sent to the display.  LOW = Command, HIGH = Data
• BLK – Backlight Control.  If left unconnected, the backlight is always on.  Pull LOW to turn off

Package Includes:

• 1 x 1.3 Inch 240×240 RGB TFT IPS LCD Display Module
• 1 x male Header Pins
