AttoPilot v3.0 AHRS IMU Complete Package

Description

The 6DOF AHRS IMU is the newest AttoPilot system on the market, the hermetic enclosure keeps internal components clean, prevents water condensation from affecting sensitive analog components, and physically protects the working PCBs. Four mounting holes and high vibration resistance make installation easy. There is typically no need for foam padding.

Sophisticated in design and rich in features but still easy to use from the hobbyist to the demanding professional. With a hyper threaded 32 bit processor running at 160 MIPS AttoPilot brings the functionality of high end autopilots within reach and scalability for the future.
