company blog about Bosch BMI270 IMU: Ultra-low Power Intelligent Motion Sensing Solution Supplied by Mingjiada Electronics

Shenzhen Mingjiada Electronics Co., Ltd. has been supplying genuine BMI270 IMU (Inertial Measurement Unit) products for a long time: an ultra-low power intelligent motion sensing solution.

BMI270 Product Description
The Bosch BMI270 is an ultra-low power 6-axis inertial measurement unit (IMU) optimised for wearable devices, integrating a 16-bit three-axis accelerometer and a 16-bit three-axis gyroscope. It features a compact 2.5mm × 3.0mm × 0.8mm package and is suitable for applications such as smartwatches, fitness trackers, and AR/VR devices.

The BMI270 is based on Bosch MEMS process technology and features a self-calibrating gyroscope (via the static component re-tuning (CRT) function), ensuring sensitivity error as low as ±0.4% after soldering. The BMI270 also supports a plug-and-play pedometer, optimising step detection accuracy for wrist-worn devices.

BMI270 Product Features
Ultra-low power consumption design
BMI270 consumes as little as 10μA in accelerometer-only mode and 685μA in full-function mode.
Operates independently of the main processor for gesture recognition and activity tracking, with power consumption as low as 30μA.
Smart motion sensing
BMI270 is available in two versions:
‘Gesture Edition’ (supports wrist flick, arm swing, etc.)
‘Scenario/Activity Edition’ (recognises standing, walking, and in-vehicle status).
Built-in 2kB FIFO reduces main controller intervention and optimises power consumption.
High Precision and Reliability
BMI270 uses automotive-grade gyroscope technology with zero bias stability of ±0.5dps and accelerometer zero bias of ±20mg.
Supports automatic MDI/MDI-X and RGMII interface optimisation to ensure signal integrity.
Flexible application adaptation
The BMI270 is pin-compatible with the BMI160/BMI260/BMI263, facilitating upgrades.
Operating voltage: 1.2V–3.6V, compatible with various wearable device power supply solutions.
