LSM6DSOTR is a highly integrated 6-axis IMU. The LSM6DSOTR features ultra-low 0.55mA power consumption. For wearable devices, LSM6DSOTR is the top choice. The LSM6DSOTR includes a 9KB FIFO buffer. We recommend LSM6DSOTR for OIS/EIS applications. Choosing LSM6DSOTR ensures reliable motion tracking.
LSM6DSOTR Product Overview
The LSM6DSOTR is an iNEMO 6‑axis inertial measurement unit (IMU) from STMicroelectronics in a system‑in‑package (SiP) that integrates a 3‑axis digital accelerometer and a 3‑axis digital gyroscope. The LSM6DSOTR draws only 0.55mA in high‑performance mode and supports always‑on low‑power features, delivering an optimal motion experience for battery‑powered consumer and IoT devices. Housed in a 14‑pin LGA package measuring just 2.5×3×0.83mm, the LSM6DSOTR supports SPI, I²C, and MIPI I3CSM serial interfaces. The LSM6DSOTR is widely used in wearables, IoT nodes, game controllers, indoor navigation, and camera optical image stabilization (OIS/EIS).
