Adafruit LIS3MDL Shield
Overview
The Adafruit LIS3MDL Triple-Axis Magnetometer Sensor Shield features a ST LIS3MDL 3-axis magnetometer and two STEMMA QT connectors.
Requirements
This shield can be used with boards which provide an I2C connector, for
example STEMMA QT or Qwiic connectors.
The target board must define a zephyr_i2c node label.
See Shields for more details.

In order to use the DRDY output you need to connect a separate wire from the
shield to a GPIO pin on your microcontroller board. See
st,lis3mdl-magn for documentation on how to adjust the
devicetree file.
Programming
Set --shield adafruit_lis3mdl when you invoke west build. For example
when running the Magnetometer Sensor sample:
# From the root of the zephyr repository
west build -b adafruit_feather_rp2040 --shield adafruit_lis3mdl samples/sensor/magn_polling
west flash
