SparkFun Micro 6DoF IMU Breakout - BMI270 (Qwiic)

The SparkFun BMI270 Micro 6DoF IMU Breakout is a Qwiic-enabled breakout board based on the ultra-low power BMI270 from Bosch. This chip is a highly integrated, low-power IMU optimized for wearables providing precise acceleration, angular rate measurement, and intelligent on-chip motion-triggered interrupt features. Not only does the BMI270 comprise a fast and sensitive accelerometer and gyro pair, but it also contains several intelligent, on-chip motion-triggered interrupt features.

Our Micro-sized 0.3in. x 0.75in. footprint makes this breakout board an ideal option for your smallest projects using our solderless Qwiic cables and compatible controllers. On-board solder jumpers allow you to easily select the device address, remove the I²C pull-ups, and disable the power LED if need be.

The 6-axis sensor combines a 16-bit tri-axial gyroscope and a 16-bit tri-axial accelerometer featuring Bosch’s automotive-proven gyroscope technology. BMI270 includes several functionalities, such as an integrated plug-and-play step counter/detector and gesture detection for wrist-worn devices. Moreover, the IMU suits wearables, smart clothes, smart shoes, smart glasses, and ankle bands.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
