Waveshare 1.14inch LCD Display Module for Raspberry Pi Pico
4+
###########################################################
5+

Overview
7+
********
8+
9+
The Waveshare 1.14inch LCD Display Module for Raspberry Pi Pico is
10+
a 240x135/65K color IPS LCD module based on the ST7789V controller.
11+
This module connects via SPI.
12+
This display module has two buttons and joystick that the user program can use.
13+
It is convenient for implementing user interfaces.
14+
15+
More information about the shield and Arduino adapter can be found at
16+
the `Waveshare Pico-LCD-1.14 Module website`_.
