FAQ

Q: What is the benefit of on-chip sensor fusion for drones?
A: The SFLP engine computes orientation at up to 240 Hz directly on the IMU, outputting quaternion, gravity, and linear acceleration through the FIFO. This saves 10–30% of MCU compute cycles that would otherwise run Madgwick/Mahony/EKF algorithms. For multi-MCU drone architectures (FC + companion

Q: How can Qvar be used for drone obstacle avoidance?
A: Qvar measures changes in electrostatic field as objects approach the sensor electrode. By placing Qvar electrodes on drone arms or body panels, the sensor detects proximity of walls, obstacles, or other drones at ranges of 5–30 cm (depending on electrode size and object material). While not a

Q: Is the LSM6DSVETR a drop-in replacement for LSM6DSV16X?
A: Yes, physically. Same LGA-14L (2.5×3×0.71 mm) package and pinout. The LSM6DSVETR adds Qvar and SFLP fusion registers while maintaining backward compatibility with LSM6DSV core registers. Firmware must enable Qvar and SFLP features to utilize the added capabilities.

1. Product Overview

The LSM6DSVETR is STMicroelectronics' advanced 6-axis IMU with an integrated Qvar electrostatic sensor and on-chip 6-axis sensor fusion engine that outputs pre-computed quaternion orientation, gravity vector, and linear acceleration directly — eliminating the need for host MCU sensor fusion computation. With 3.2 mdps/√Hz gyro noise, 70 µg/√Hz accel noise, ±4000 dps gyro range, MLC, FSM, ASC, and the unique Qvar channel, it is the most sensor-rich IMU in the LSM6DSV family. The on-chip fusion engine computes AHRS (Attitude and Heading Reference System) output at the sensor ODR, enabling low-power MCUs to access orientation data without running computationally expensive Madgwick/Mahony/EKF algorithms. For advanced drone applications, the LSM6DSVETR offers
