st7789 tft display supplier

This 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.

The module interface is SPI, to make the display small the CS pin is not breakout, but you can still drive it without connecting a CS pin, here is a library working library for this particular display, to make it working properly, you also need to install Adafruit’s GFX library.

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.

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.

Though these displays can seem to be a bit intimidating to use at first, especially with a lack of a CS pin, just follow these steps to get up and running very easily.

Install the Arduino-ST7789-Library.  You will need to manually downloadit from the GitHub site as it is not available via the Arduino IDE library manager.  This library is a modified version of the original Adafruit library which makes it easy to use with the displays that do not have a CS pin as well as those that do.  https://github.com/ananevilya/Arduino-ST7789-Library

This change uses the hardware SPI lines on the MCU for fastest operation.  You can also use Software SPI by uncommenting this line instead: //Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST, TFT_MOSI, TFT_SCLK); //for display without CS pin which is slower, but allows you to use any pins you want for the SPI interface.

We"ve been looking for a display like this for a long time - it"s so small only 1.3" diagonal but has a high density 260 ppi, 240x240 pixel display with full-angle viewing.

It looks a lot like the 1.44" 128x128 display, but has 4x as many pixels and looks great at any angle. We"ve seen displays of this caliber used in smartwatches and small electronic devices but they"ve always been MIPI interface. Finally, we found one that is SPI and has a friendly display driver, so it works with any and all microcontrollers or microcomputers!

This lovely little display breakout is the best way to add a small, colorful and very bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! The 1.3" display has 240x240 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 (ST7789) is very similar to the popular ST7735, and our Arduino library supports it well.

This breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. There was a little space so Adafruit placed a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card. The microSD card is not included

In the above example, Node32-Lite and this 0.96-inch LCD.  Please refer to the tutorial here: ST7789 interfacing with ESP32 to make the connections, Arduino library installation, and modification needed for it to works on this LCD.

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.
