We heard you like sensors (we definitely like sensors!). So we combined three of our favourite ones into a convenient, small, stick-shaped format perfect for adding additional smarts to many different projects. The onboard I2C sensors can detect:

• Temperature
• Pressure
• Humidity
• Light
• Proximity
• Orientation
• Motion (including steps, single and double taps and freefall

It has a Qw/ST (also known as STEMMA QT and Qwiic) connector at each end to make it easy to connect it up to Qw/ST compatible microcontrollers, HATs and other boards via cable. Qw/ST cables are sold separately.

Software

If you plan on using the Multi-Sensor Stick withRaspberry Pi Pico(or another RP2040/RP2350 microcontroller) there are drivers for BME280 and LTR559 baked into our custom MicroPython builds. We’ve spun up a new standalone MicroPython library for LSM6DS3 – search forlsm6ds3-micropythonin Thonny’s ‘Manage Packages’ to install it.
