Accelerometer (ICM-20948)

Accelerometer (ICM-20948)

SKU:AX22-0052

Add advanced motion sensing to any project with this 9-axis IMU module. The ICM-20948 combines a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer in one compact package, giving you complete orientation tracking and motion detection. Perfect for robotics, drones, gesture control, or any application needing precise movement data. The onboard Digital Motion Processor handles sensor fusion internally, offloading complex calculations from your microcontroller. Two STEMMA QT connectors make I²C daisy-chaining simple, while the interrupt pin lets you wake on motion or data-ready events. Solder jumpers on the back let you switch from I²C to SPI protocol if you need faster data rates. Drop it into any AX22 backplane and start tracking motion in 3D space with Arduino IDE, MicroPython, or MicroBlocks.
