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.

Jargon buster

Plain-language definitions for the technical terms used above.

Axial: Axial components have one lead coming out of each end, so they lie flat or span holes on a circuit board or breadboard. This matters when checking whether the resistor will physically fit your prototyping or through-board assembly method.
breakout: A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
Gyroscope: A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.
IMU: An IMU (Inertial Measurement Unit) combines motion sensors, typically an accelerometer and gyroscope and sometimes a magnetometer, to measure movement and orientation. It can sense motion, tilt, vibration, rotation, and changes in direction, which is useful for tasks such as navigation, stabilisation, gesture detection, and asset tracking.
LED: A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
PCB: A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
Qwiic: Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
UPS: An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
