DAIMU 351: Tactical-Grade IPX68 Waterproof High-Precision Inertial Navigation Module

The DAIMU351 is a tactical-grade high-performance Inertial Measurement Unit (IMU) designed for high-difficulty industrial and autonomous driving scenarios. This product integrates multiple sensors and an MCU, achieving tactical-grade precision with a gyroscope bias instability of 0.2°/hr and an accelerometer bias instability of 30μg. It incorporates complementary filtering and Kalman filtering (EKF/UKF) algorithms for three-axis attitude angles, delivering top-tier attitude accuracy with a roll of 0.01°, pitch of 0.01°, and yaw of 0.1°. The housing features an anodized surface treatment process, with dimensions of 43.5×43.5×28mm. It supports stable operation across the full temperature range of -40℃ to 85℃, and boasts IPX68 highest waterproof and dustproof rating, 2000g shock resistance, 10g vibration resistance, and 100% magnetic shielding. Verified through rigorous processes including independent turntable calibration and temperature drift compensation across four major production line stations, it achieves a single-board test yield of 99.9% and stable operation for >1000 hours, making it a core perception component for high-end equipment such as UAVs, autonomous driving systems, and industrial robots.
