Product description: IPS TFT display 1.9'' 320x170px - SPI - ST7789 - Adafruit 5394
IPS TFT display with a diagonal of 1.9" and a resolution of 320 x 170 px , equipped with the ST7789 controller. It is characterized by 16-bit color depth and viewing angles up to 80°. The built-in system allows communication using the SPI interface via appropriate soldering pins , or the EYESPI connector on the board - an 18-pin FPC tape with a 0.5 mm pitch. The logic level converter and voltage regulator used allow the display to be used with both 3.3 V and 5 V voltages. There is also a place here. to a microSD card where bitmaps ready to be displayed can be stored.
The display is compatible with Arduino and Raspberry Pi !
The manufacturer has prepared ready-made Arduino and Circuit Python libraries to facilitate the use of the display.
Elements included in the set.
IPS TFT display 1.9'' 320x170px - SPI - ST7789 - Adafruit 5394.
Pinouts of the display module
The module is equipped with an EYESPI connector, allowing connection to other devices via a dedicated 18-pin FPC tape with a pitch of 0.5 mm. The user can also use 11 pins to which, for example, a goldpin strip with a pitch of 2.54 mm can be soldered. The available outputs include:
- V+ / VIN - power supply to the module from 3 V to 5 V
- 3V / 3Vo - output from the built-in 3.3 V regulator, efficiency 100 mA
- G / GND - common ground of the system
- CS/SCK - clock pin of the SPI interface
- SI / MOSI - SPI interface pin, used to receive data from the microcontroller
- SO / MISO - SPI interface pin, used to transfer data from the SD card
- TC /TFTCS - Chip Select pin of the TFT display
- RT / RST - TFT display reset
- DC - choice between sending data and commands via the SPI interface
- CC/SDCD - Chip Select pin of the micro SD card
- BL / Lite - PWM input to control the display backlight
To prevent the backlight from peeling off, use a layer of glass or plastic to lightly press against the display.
