Datasheet (BMI270)Product Overview
The SparkFun BMI270 6DoF IMU Qwiic Breakout delivers highly precise acceleration and angular-rate measurements, plus a sophisticated on-chip motion-interrupt engine, for optimized motion tracking in an ultra-low-power wearable package. Operating efficiently at both 1.8V and 3.3V, this 16-bit sensor from Bosch Sensortec handles complex tasks like gesture detection and step counting internally, freeing up your microcontroller for other operations while integrating effortlessly into your system via solderless Qwiic connectors.

Intelligent Motion Tracking & Customization
The reason why we really like the BMI270 is primarily thanks to its integrated smart features and measuring capabilities, both of which are typically found in smartwatches, fitness trackers, augmented/virtual reality glasses, and more. The BMI270 breakout processes the data it collects all the while actively monitoring for specific physical events.
- Built-in Detection: Uses pre-loaded smart algorithms for any-motion detection, no-motion detection, activity change recognition, wrist-wear wake-up, plug-and-play step counting, and wrist gesture recognition.
- Selectable Ranges: Includes a 16-bit 3-axis accelerometer with four configurable measurement ranges of ±2g, ±4g, ±8g, and ±16g, alongside a 16-bit 3-axis gyroscope with five configurable measurement ranges of ±125dps, ±250dps, ±500dps, ±1000dps, and ±2000dps.
- Hardware Interface: Provides a 400kHz AUX sensor interface with hardware synchronization to easily pull data from secondary peripherals.
The breakout communicates natively over I2C (defaulting to address 0x68) using the dual horizontal Qwiic connectors on the standard 1-inch by 1-inch footprint. Standard 0.1-inch-spaced pins remain available along the board edge for users who prefer a soldered connection, and onboard solder jumpers let you change the I2C address, remove the pull-up resistors, or disable the power LED.
