MinIMU-9 v5 Gyro, Accelerometer, and Compass (LSM6DS33 and LIS3MDL Carrier) DACs We found the smallest PS/2+USB

We found the smallest PS/2+USB keyboard available

Mounting Hole dimensions: 20mm x 12mm apart

or when serial data is received

This allows you to have two AltIMUs (or an AltIMU v5 and a MinIMU v5) connected on the same I²C bus

Here is an example video that Adafruit put together:

MinIMU-9 v5 Gyro, Accelerometer, and Compass (LSM6DS33 and LIS3MDL Carrier) DACs We found the smallest PS/2+USBThe Pololu MinIMU 9 v5 is an inertial measurement unit (IMU) that packs an LSM6DS33 3 axis gyro and 3 axis accelerometer and an LIS3MDL 3 axis magnetometer onto a tiny 0. 8 0. 5 board. An IC interface accesses nine independent rotation, acceleration, and magnetic measurements that can be used to calculate the sensors absolute orientation. The MinIMU 9 v5 board includes a voltage regulator and a level shifting circuit that allow operation from 2. 5 to
