The UM6 r2 ultra-miniature orientation sensor from CH Robotics uses rate gyros, accelerometers, magnetic sensors, and an onboard 32-bit ARM Cortex processor to compute sensor orientation 500 times per second. Sensor orientation is reported using either quaternions or Euler angles over a TTL serial interface at user-customizable rates. The UM6 was designed specifically to be easy to use—an external enclosure protects sensitive electronics, and connectors make it easy to interface with the sensor without making solder connections to the sensor itself.

The Pololu AltIMU-10 v3 is an inertial measurement unit (IMU) and altimeter that features the same L3GD20D gyro and LSM303D accelerometer and magnetometer as the MinIMU-9 v3, and adds an LPS331AP digital barometer. An I²C interface accesses ten independent pressure, rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s altitude and absolute orientation. The board operates from 2.5 to 5.5 V and has a 0.1″ pin spacing.

The Pololu MinIMU-9 v3 is an inertial measurement unit (IMU) that packs an L3GD20H 3-axis gyro and an LSM303D 3-axis accelerometer and 3-axis magnetometer onto a tiny 0.8″ × 0.5″ board. An I²C interface accesses nine independent rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s absolute orientation. The MinIMU-9 v3 board includes a voltage regulator and a level-shifting circuit that allows operation from 2.5 to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.

This product has been discontinued.

A new version of this product should be available in May or June. Please consider the UM6 r2 as an immediately available alternative.

The UM6-LT ultra-miniature orientation sensor from CH Robotics is an OEM version of their UM6 orientation sensor, providing equivalent functionality without the enclosure or connectors. Like the UM6, it uses rate gyros, accelerometers, magnetic sensors, and an on-board 32-bit ARM Cortex processor to compute sensor orientation 500 times per second. Sensor orientation is reported using either quaternions or Euler angles over a TTL serial interface at user-customizable rates.
