LSM6DSL – 3D accelerometer and 3D gyroscope
Two low-power 6-axis inertial modules introduced from STMicroelectronics, the LSM6DSL and LSM6DSM. Both they pack a 3-D digital accelerometer and a 3-D digital gyroscope in a miniature package. These modules consume 0.4 mA in combo normal mode and 0.65 mA in combo high-performance...
