1.3″ SPI Colour Round LCD (240×240) Breakout
$31.20
High-res and vibrant, with sweet viewing angles (IPS), this 1.3″ round LCD screen will add some stylish curves to your Raspberry Pi projects.
ow … ound … round … ground – this unconventional round display is ideally shaped for things like watch faces, speedometers and displaying data in interesting circular ways like pie charts and polar area graphs. You could also use it to add animated eyes to cosplay masks, build a moon phase tracker or just for displaying all the best round GIFs of pizzas, hypnotic spirals and chonky animals.
Description
This IPS display so it has great viewing angles and it’s super-crisp and bright. It’s driven by SPI and you should be able to run it at up to ~60FPS, although we’ve found that anywhere from 10FPS looks good for most uses.

ST7789 driver chip
Software
This breakout uses the same ST7789 library as the square version. The library makes it straightforward to display images, text or graphics, and even display animated GIFs! If you’re using a Raspberry Pi, you can install it with:
sudo pip3 install st7789
You may also need to enable I2C and SPI in raspi-config.
When running the generic examples, you’ll need to specify that you’re using a round display to offset the screen correctly, e.g.
python3 gif.py deployrainbows.gif round
You can also use this breakout with Raspberry Pi Pico and other RP2040 boards, using C++ or Pirate brand MicroPython.
Connecting to a Raspberry Pi
If you’re not using a Breakout Garden, then this is how to connect your LCD Breakout up to your Raspberry Pi.
Our Python library is set up to use SPI 0 by default on the Pi (BCM 7 for CS, BCM 11 for SCK, and BCM 10 for MOSI), BCM 9 for DC, and BCM 19 for the backlight.
Here’s which pins to connect between your LCD breakout and your Pi’s GPIO (note that it’s BCM pin numbering):
3-5V to any 5V or 3V pin
CS to BCM 7
SCK to BCM 11
MOSI to BCM 10
DC to BCM 9
BL to BCM 19
GND to any ground pin
You can of course use other pins with your LCD Breakout, but you’ll have to change them accordingly when you instantiate the display in your code.
Connecting to a Raspberry Pi Pico
If you’d rather wire them up to a Pico directly, here’s how it goes!
3-5V to any 5V or 3V pin
CS to GP17
SCK to GP18
MOSI to GP19
DC to GP16
BL to GP20
GND to any ground pin
