Summary

The 1.69inch LCD module by Waveshare uses the ST7789V2 driver with an SPI interface and a 240×280 pixel resolution. It supports 16-bit colors (RGB565), operates at 3.3V/5V, and is designed for Raspberry Pi, STM32, and Arduino.

Technical overview

  • Resolution: 240(H) × 280(V) pixels; display size approx. 27.972 mm × 32.634 mm
  • Driver IC: ST7789V2; supports RGB444, RGB565 and RGB666 color formats; demo uses RGB565
  • Interface: 4-wire SPI (MOSI, SCLK, CS, DC, RST); CPOL=0, CPHA=0; data transmitted MSB first
  • Power supply: 3.3 V or 5 V; supply voltage and logic voltage must be identical, otherwise the module will not work properly
  • Module dimensions: 31.5 mm × 39.0 mm; pixel pitch 0.11655 mm
  • Rounded corners may cause parts of input images to be clipped
  • Maximum power consumption: 90 mA at 3.3 V; maximum brightness: 500 cd/m² at 3.3 V
  • Supported platforms: Raspberry Pi (C/Python demos), STM32, Arduino; FBCP framebuffer integration also documented

Commands and examples – verify before use:  

sudo raspi-config → Interfacing Options → SPI → Yes
ls /dev/spi*
sudo ./shell/waveshare-1inch69
sudo cmake -DSPI_BUS_CLOCK_DIVISOR=20 -DWAVESHARE_1INCH69_LCD=ON -DBACKLIGHT_CONTROL=ON -DSTATISTICS=0 ..
sudo make -j
sudo ./fbcp
sudo python3 1inch69_LCD_test.py
sudo ./main 1.69

Notes and version constraints

  • Raspberry Pi pin mapping depends on the specific Pi revision; the provided table applies to certain revisions and should be verified before wiring.
  • FBCP scripts overwrite /boot/config.txt and /etc/rc.local and trigger a reboot; backing up these files is recommended.
  • Demo files are downloaded from external URLs; availability may vary.
  • STM32 and Arduino sections contain only headings; hardware connection and demo details are missing from the supplied text.
  • The source contains template placeholders ({{{...}}), indicating incomplete documentation; technical values should be cross-checked against the ST7789V2 datasheet.
