Description
1.3″ TFT Display with IPS Panel and 65k colours.
The ST7789 display controller requires 3.3V power supply and logic level.
Backlight control pin BLK is low-active.
Please note: The module doesn’t have a Chip-Select pin. Therefore, it is not possible to connect it together with other SPI devices to the same bus.
Module dimension: 28 x 39mm
Screen dimension: 23 x 23mm
Mounting holes: 2mm
Like always, libraries for ST7789 (for example for Arduino) are available on GitHub.
Please understand and accept, that the picture show only one make of these displays, but we can also have a different make (from a different factory) in stock. These displays are absolutely identical, but the PCBs look maybe a little different.
A larger 2.4″ colour TFT (shield for Arduino UNO or MEGA) is also available from UNIVERSAL-SOLDER.
m.p (verified owner) –
This display is bright, sharp, and has a wide viewing angle (both up/down and left/right).
As the description states, it’s 3.3V, and it’s SPI despite the data and clock pins being labelled SDA and SCL on the one I received. I connected it to a 3.3V Arduino Pro Mini using the following pins:
– GND -> GND
– VCC -> VCC
– SCL -> 13 (SCK)
– SDA -> 11 (MOSI)
– RES -> 9
– DC -> 8
– BLK -> no connection
There are several popular libraries out there that work with this display. It took me a little longer to get it working than I expected but that was because with no CS pin, the SPI mode needs to be set to SPI_MODE2. With that set, it works like a charm!
This display (like many others) is very fragile and will be damaged if it’s not protected. The one I received came in a small plastic box that no longer fit when I soldered the pins on so I cut a small hole in the box so the pins could stick through.
Long story short: it looks great, it’s 3.3V, use SPI_MODE2, and the price is very good.
