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 is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine 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 Inertial Measurement Unit combines motion sensors to measure movement and orientation. It matters for asset tracking because it can detect movement, tilt, vibration, or changes in direction.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- 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.
