The SparkFun BMI270 Micro 6DoF IMU Breakout is an ultra-low power, Qwiic-enabled board, designed with a highly-integrated IMU that's perfect for wearables. It provides precise acceleration and angular rate measurement, coupled with intelligent on-chip motion-triggered interrupt features. The BMI270 chip is not just a fast and sensitive accelerometer and gyro pair, but also contains several smart, on-chip motion-triggered interrupt features.
The breakout board has a micro-sized footprint of 7.62mm x 19.05mm, making it an excellent choice for your tiniest projects. It can be easily connected with solderless Qwiic cables and compatible controllers. The board also includes solder jumpers, which allow you to select the device address, remove the I²C pull-ups, and disable the power LED if required.
The 6-axis sensor of this board combines a 16-bit tri-axial gyroscope and a 16-bit tri-axial accelerometer, featuring Bosch’s automotive-proven gyroscope technology. The BMI270 also includes a variety of features such as an integrated step counter/detector and gesture detection for wrist-worn devices. This makes it suitable for various wearable devices like 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, which reduces the required PCB space. The polarized connections ensure you can’t connect it incorrectly.
Features of the SparkFun BMI270 Micro 6DoF IMU Breakout include a 16-bit 3-axis accelerometer with various ranges, a 16-bit 3-axis gyroscope, a 400kHz AUX sensor interface with hardware synchronization, I²C Addresses: 0x68 (default), 0x69, 1.8V and 3.3V operation, ultra-low current consumption, and several smart features like significant motion detection, activity change recognition, and wrist gesture recognition.
