9-DoF IMU Qwiic Breakout - ICM-20948 (SEN-15335)

9-DoF IMU Qwiic Breakout - ICM-20948 - Sparkfun SEN-15335

The SparkFun 9DoF IMU Breakout uses all of the features of ICM-20948 from Invensense and breaks them out to a Qwiic cable. This board has a built-in logic shifter and GPIO pins broken out for all your motion-sensing needs.

The ICM-20948 itself is an extremely low-power device. It is an I²C and SPI enabled 9-axis motion tracking device that is ideally suited for smartphones, tablets, wearable sensors, and IoT applications.

By utilizing the Qwiic system, it means that you don't need to solder in order to connect it to the rest of your system. 0.1"-spaced pins are still present 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 the 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.
