QST (Shanghai) QMI8658 is a 6-axis MEMS IMU chip in a 2.5×3.0×0.86 mm 14-pin LGA package: gyro ±16~±2048 °/s with 15 mdps/√Hz noise density, accelerometer ±2~±16 g; I3C/I2C/SPI interfaces, −40 to +85 °C operation, on-chip temperature sensor with compensation and on-chip self-calibrated 9-axis fusion. Aimed at highly integrated designs such as drones and robot vacuums, it also serves as a chip-scale sensing option for robots.
