The Pololu AltIMU-10 v5 is a compact inertial measurement unit (IMU) and altimeter that combines a gyroscope, accelerometer, magnetometer, and barometric pressure sensor on a single board. It provides ten independent measurements — pressure, 3-axis rotation, 3-axis acceleration, and 3-axis magnetic field — enabling calculation of altitude and absolute orientation.
All sensors communicate over a single I²C interface, and the board includes an on-board 3.3V regulator with level-shifted I²C lines, making it compatible with both 3.3V and 5V systems.
Key Features
- 10 Degrees of Freedom – Gyroscope, accelerometer, magnetometer, and barometer in one compact board
- LSM6DS33 – 3-axis gyro (±125 to ±2000°/s) and 3-axis accelerometer (±2 to ±16g)
- LIS3MDL – 3-axis magnetometer (±4 to ±16 gauss) for compass heading
- LPS25H – Barometric pressure sensor (260–1260 mbar) for altitude measurement
- I²C Interface – Single bus for all sensors with configurable slave addresses
- On-Board Regulator – 3.3V output with level-shifted I²C lines
- Wide Supply Voltage – Operates from 2.5V to 5.5V

Jargon buster
Plain-language definitions for the technical terms used above.
- 3.3V regulator
- A 3.3V regulator is a power circuit that provides a steady 3.3 volts for parts that need that supply voltage. On a breakout board, it can let the sensor run safely even when the connected microcontroller or power source uses a higher voltage.
- Gyroscope
- A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.
- IMU
- An IMU (Inertial Measurement Unit) combines motion sensors, typically an accelerometer and gyroscope and sometimes a magnetometer, to measure movement and orientation. It can sense motion, tilt, vibration, rotation, and changes in direction, which is useful for tasks such as navigation, stabilisation, gesture detection, and asset tracking.
- magnetometer
- A sensor that measures magnetic fields, often used to work out compass direction. It matters because nearby magnets, motors, or metal objects can affect readings and may require calibration.
- UAV
- UAV stands for Unmanned Aerial Vehicle, an aircraft that flies without an onboard pilot, such as a drone or autonomous aircraft. Because airborne platforms have limited payload, factors like weight, power draw and any positioning features such as GNSS or RTK are often important considerations.
