SparkFun 9DoF IMU Breakout - ICM-20948 (Qwiic)

The SparkFun 9DoF IMU Breakout incorporates all the amazing features of Invensense's ICM-20948 into a Qwiic-enabled breakout board complete with a logic shifter and broken out GPIO pins for all your motion sensing needs. The ICM-20948 itself is an extremely low powered, I²C and SPI enabled 9-axis motion tracking device that is ideally suited for smartphones, tablets, wearable sensors, and IoT applications. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

In addition to the 3-Axis Gyroscope with four selectable ranges, 3-Axis Accelerometer, again with four selectable ranges, and 3-axis magnetometer with an FSR to ±4900µT, the ICM-20948 also includes a Digital Motion Processor that offloads the computation of motion sensing algorithms from the detectors, allowing optimal performance of the sensors. We've also broken out all the ICM-20948 pin functionality to GPIO and labeled them I²C on the front, SPI on the back for ease of identification.

Note: The I²C address of the ICM-20948 is 0x69 and is jumper selectable to 0x68. A multiplexer/Mux is required to communicate to multiple ICM-20948 sensors on a single bus. If you need to use more than one ICM-20948 sensor consider using the Qwiic Mux Breakout.

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 canâ��t hook it up wrong.
