SparkFun 9DoF IMU (ICM-20948) Breakout Hookup Guide
The SparkFun 9DoF IMU Breakout incorporates all the amazing features of Invensense's ICM-20948 into a Qwiic-enabled breakout board replete with logic shifting 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. Featuring a 3-Axis Gyroscope with four selectable ranges, a 3-Axis Accelerometer, again with four selectable ranges, a 3-axis compass with a wide range to ±4900 µT, and an on-board Digital Motion Processor, this little breakout can even detect the motion of invisibility cloaks. Not really. Just checking to see if you were still with me. But it is pretty amazing. Check it out:
In this hookup guide, we'll connect our sensor up to our Esp32 Thing Plus microcontroller and run a of quick (Qwiic) example to get you up and running with this fantastic board!
To follow along with this tutorial, you will need the following materials. You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.
If you choose to utilize the broken out GPIO, you will need a soldering iron, solder, and general soldering accessories.
If you aren't familiar with the Qwiic system, we recommend reading here for an overview.
