SI‑MIMU‑P 10‑Axis MEMS IMU | ADIS16488 Pin-to-Pin Replacement for UAV Attitude Control
The TJ-MIMU-P Micro Inertial Measurement Unit (MIMU) is a professional inertial measurement device built on mature Micro-Electro-Mechanical System (MEMS) technology. It integrates a built-in three-axis MEMS gyroscope, three-axis MEMS accelerometer, three-axis magnetometer and barometric pressure sensor, matched with dedicated drive and signal acquisition circuits, temperature sensors, digital signal processing circuits, mechanical structures and supporting embedded software.
Adopting a proprietary structural design and equipped with comprehensive compensation algorithms covering full-temperature range, installation misalignment and nonlinearity, the MIMU delivers steady and reliable performance in static, dynamic and harsh working environments, providing high-stability measurement data for various application scenarios.
