Aspirin V1.3 top view


Aspirin IMU

The next generation flat multi degree of freedom inertial measurement unit. It uses digital 3-axis sensors which allow for a very small size and price. Other features include onboard voltage regulators, EEPROM for storing calibration data and extra sensors such as a barometer.
