# Adafruit LSM9DS1 9-DoF IMU

> Adafruit 4634 LSM9DS1 9-DoF IMU (STEMMA QT): ST LSM9DS1 accelerometer ±2/4/8/16 g, gyroscope ±245/500/2000 dps, magnetometer ±4/8/12/16 gauss — the same IMU as the Arduino Nano 33 BLE. Raw 9-axis data for your own fusion (no on-chip fusion), I2C or SPI with separate accel/gyro and magnetometer selects, 3–5 V supply and logic, 1.0 × 0.7 in board with two mounting holes.
