+Waveshare 1.3inch OLED Display Module for Raspberry Pi Pico
+###########################################################
+
+Overview
+********
+
+The Waveshare 1.3inch OLED Display Module for Raspberry Pi Pico is
+a 64x128 vertically long LCD module based on the SinoWealth SH1107 controller.
+This module connects via I2C and optionally can use SPI(need soldering).
+This display module has two buttons that the user program can use.
+It is convenient for implementing user interfaces.
+
+More information about the shield and Arduino adapter can be found at
+the `Waveshare Pico OLED 1.3 Module website`_.

+
+.. note::
+   The SPI interface is not available by default.
+   Switch the J1, J2, and J3 jumper by moving 0-ohm registers
+   to the SPI side to enable SPI.
+
+Programming
+***********
+
+Set ``-DSHIELD=waveshare_pico_oled_1_3`` when you invoke ``west build``. For example:
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/subsys/display/lvgl
+   :board: rpi_pico
+   :shield: waveshare_pico_oled_1_3
+   :goals: build
