IMU-G-1020-S is an industrial 6-axis IMU module from Shenzhen SZLIGHT (SZLCTEK), built on a purple PCB (V1.0, 2025-08-29) around a HiPNUC HI14-series MEMS inertial chip (silkscreen HIPNUCHI14). The HI14 family offers gyro ranges of ±2000 to ±4000 °/s and accelerometer ranges of ±24 to ±32 g, outputs fused Euler angles and quaternions at up to 1000 Hz over UART/USB, and applies full-temperature compensation from -40 to +85 °C for harsh outdoor environments. This board breaks out 5V/GND, TXD/RXD, an RSYNC sync pin and RS-485 (485A/485B) through an 8-pin connector, targeting robot attitude sensing and stabilization. No public page exists for the module vendor, so core specs follow the official HiPNUC HI14 datasheet.

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.
Bosch Sensortec (Germany) BMI088 is a high-performance inertial measurement unit purpose-built for drones and robots, providing highly accurate orientation and motion measurement along three orthogonal axes with excellent temperature stability. Accelerometer range selectable from ±3/±6/±12/±24 g with 16-bit resolution of 0.09 mg, 175 µg/√Hz noise density and programmable 5~523 Hz bandwidth; gyro range ±125 to ±2000 °/s with 16-bit resolution of 0.004 °/s, 0.014 °/s/√Hz noise density and output data rates of 12.5 Hz to 2 kHz. Zero offset (typ. over lifetime) is ±20 mg (accel) and ±1 °/s (gyro) with TCO of ±0.2 mg/K and ±0.015 °/s/K respectively. SPI/I²C interfaces, 2.4~3.6 V supply at 5.15 mA full-operation current, −40 to +85 °C — a classic choice for flight/attitude control on racing drones, robot dogs and humanoid robots.
TDK InvenSense ICM-42688-P is the flagship 6-axis SmartIndustrial™ MotionTracking MEMS device for robotics and high-performance IoT, combining a 3-axis gyro and 3-axis accelerometer. Gyro noise is only 2.8 mdps/√Hz and accelerometer noise 70 µg/√Hz, with 6-axis current as low as 0.88 mA in low-noise mode; gyro full scale is selectable from ±15.6 to ±2000 dps and accelerometer from ±2 to ±16 g, with user-programmable digital filters. Host interfaces include 12.5 MHz I3C, 1 MHz I²C and 24 MHz SPI in a thin 2.5 × 3 × 0.76 mm 14-pin LGA package with drop-in 6-axis footprint compatibility. Officially targeted at AR/VR/XR, robotics and high-performance IoT, it is one of the most widely used consumer/industrial IMUs for joint and body attitude sensing on humanoid robots and robot dogs.
Wit Motion (Shenzhen) WT61 is a cost-effective 3-D attitude measurement system based on MEMS technology, integrating a 3-axis gyroscope and 3-axis accelerometer. Its proprietary Kalman-filter sensor-fusion algorithm outputs temperature-compensated 3-axis attitude angles at up to 100 Hz in real time. Accelerometer ±16 g range with 0.0005 g/LSB resolution and 0.75~1 mg RMS noise at 100 Hz bandwidth; gyro ±2000 °/s with 0.05 °/s RMS noise; 0.2° roll/pitch accuracy and 0.5° static heading accuracy (6-axis algorithm). The module ships with a metal shield case for good EMI immunity and easy mounting, making it one of the most popular entry-level IMUs for humanoid robots, robot dogs, AGVs, gimbals and education.
