1.3" Inch 240*240 RGB TFT IPS LCD Module 7pin
ST7789 Chip
Features
- 1.3″ TFT LCD with wide ±80° viewing angle
- RGB Full color display
- 240 x 240 high resolution 260PPI display
- SPI interface w/out CS pin
- ST7789 LCD display controller
- 3.3 operation
Operates at 3.3V, so if using with a 5V MCU, include logic level shifters on the data lines to prevent damage. The module don't have a 3.3V regulator so you must power with 3.3V.
This is a write only device and doesn't need the SPI MISO line hooked up. The module also doesn't bring the CS pin out to the interface which helps to lower the pin count. Unfortunately, it can't be used with other SPI devices on the same bus simultaneously.
Connecting the display via a 7 pin header.
1 x 7 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
EVALUATION
Breadboard friendly with a 7-pin header on the back. It can be inserted into a breadboard or a 7-pin female connector to mount the display. PCB mounted display which helps provide support. Don't press on the glass portion of the display when inserting into a breadboard. Use the pin headers.
Display Connection
Connect VCC to 3.3V and GND to ground on the MCU.
Connect the SPI lines. SCL goes to the SPI SCL line on the MCU and SDA goes to the SPI MOSI line on the MCU. This pins will be different depending on the MCU. On the Arduino UNO, the SPI SCL is pin 13. On the Arduino MEGA 2560, it is pin 52. MOSI is pin 11 on the Uno and pin 51 on the Mega 2560.
Connect DC to pin 8 and RST to pin 9. The BLK pin can be left unconnected and will leave the backlight on.
When using a 3.3V MCU, the lines can be connected directly. If using a 5V MCU, then you need to use a logic level converter.
