1.3″ SPI Colour Square LCD (240×240) Breakout

Description

The square form-factor of this display makes it great for cramming lots of information on—data, graphs, even things like album art and photos. Like our smaller 0.9″ LCD breakout, this one is an 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 ~50FPS, although we’ve found that anywhere from 10FPS looks good for most uses.

Software

We’ve adapted an existing Python library to drive this display. The library makes it straightforward to display images, text or graphics, and even display animated GIFs!

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

The 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 0.96″ 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 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
