LSM6DSL iNEMO Inertial Module, Always-on 3D Accelerometer and 3D Gyroscope

The LSM6DSL is an iNEMO inertial module from STMicroelectronics that combines a 3D digital accelerometer and a 3D digital gyroscope. It is highly power efficient, using only 0.65 mA in its high-performance setting, making it ideal for continuous, low-power applications. It has the dynamic data storage capacity up to 4 Kbytes. Built on ST’s established MEMS sensor production techniques, the LSM6DSL ensures reliability and precision. The sensors are crafted using advanced micromachining, and the internal circuits are designed with CMOS technology for optimal performance. With acceleration capabilities ranging from ±2 to ±16 g and angular speeds from ±125 to ±2000 dps, it's a robust choice for many applications. Its resilience to shocks and disturbances further cements its reliability. The LSM6DSL is packaged in a compact plastic land grid array (LGA).
