Adafruit LIS3DH Shield

Overview

The Adafruit LIS3DH Triple-Axis Accelerometer Sensor Shield features a ST LIS3DH 3-axis accelerometer 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.

Pin Assignments

Shield Pin	Function
SDA	LIS3DH I2C SDA
SCL	LIS3DH I2C SCL
INT	LIS3DH Interrupt out
SDO	LIS3DH I2C address selection. Pull down by default.
CS	LIS3DH Force I2C mode by setting it to high level.
I2	LIS3DH Second interrupt out
A1-A3	LIS3DH Analog-to-digital converter inputs. Not used.

In order to use interrupts you need to connect a separate wire from the shield to a GPIO pin on your microcontroller board. See st,lis3dh for documentation on how to adjust the devicetree file.

Programming

Set --shield adafruit_lis3dh when you invoke west build. For example when running the Generic 3-Axis accelerometer polling sample:

# From the root of the zephyr repository
west build -b adafruit_qt_py_rp2040 --shield adafruit_lis3dh samples/sensor/accel_polling
