描述

SparkFun 9DoF IMU Breakout – ICM-20948 (Qwiic) 加速度計 陀螺儀 磁力計

SparkFun 9DoF IMU Breakout 將 Invensense ICM-20948 的所有驚人功能集成到支持Qwiic的分線板中，該分線板具有邏輯移位器和GPIO引腳，可滿足您所有的運動感測需求。ICM-20948本身是一款功耗極低，支持I ² C和SPI的9軸運動跟踪設備，非常適合智能手機，平板電腦，可穿戴傳感器和IoT應用。利用我們方便的Qwiic系統，無需焊接即可將其連接到系統的其餘部分。但是，如果您更喜歡使用麵包板，我們仍然會斷開0.1英寸間距的插針。

除了具有四個可選範圍的3軸陀螺儀，再次具有四個可選範圍的3軸加速度計以及具有FSR至±4900µT的3軸磁力計之外，ICM-20948還包括一個數字運動處理器，可減輕計算負擔來自檢測器的運動感應算法，可實現傳感器的最佳性能。我們還將ICM-20948的所有引腳功能都分解為GPIO，並在前面將它們標記為I ² C，在後面標記為SPI，以便於識別。

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.
