Description


Adafruit 1.9" 320x170 Color IPS TFT Display LCD Driver unit

Adafruit 1.9" 320x170 Color IPS TFT display has 320x170 16-bit full-color pixels and is an IPS display, so the color looks great up to 80 degrees off-axis in any direction.

The TFT driver (Sitronix ST7789) is very similar to the popular ST7735.

Details:

ST7789

Width: 170 Height: 320

SPI Mode: 0 SPI Frequency: 42000000 SPI Chip Select: SPI_CS_0

DC GPIO: GPIO_PIN_25 (Pull: GPIO_PULL_NONE) RST GPIO: GPIO_PIN_27 (Pull: GPIO_PULL_NONE)

Backlight GPIO: GPIO_PIN_18 (GPIO / PWM)
