Pluto N1 is designed for geeks and robot enthusiasts. It is ultra-compact low-cost Enhanced Attitude and Heading Reference System (E-AHRS), not only providing 2D navigation solution for UGV such as self-balancing scooters, but also 3D navigation solution for UAV and UUV application. The output rate of N1 reaches 500HZ maximally, integrating 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetic meter as well as barometer and thermometer. Inertial sensor was temperature-compensated by -10~75 C
