ICM-20948 Low-power 9-Axis MEMS Motion Tracking Device Sensor 20948Item NO.: ICM-20948 Motion Sensor

ICM-20948

Motion Tracking Sensor Module

Product Overview:

ICM-20948 is specially designed to coordinate the time between ICM-20948 and external sensors. An additional function. In addition to using the dedicated interrupt INT pin of the module, developers can also use the interrupt or synchronization pulse of the external sensor to drive the FSYNC pin of the module to help developers simplify these multisensor designs.

ICM-20948 provides independent external sensors. 12C interface and built-in support. Here the developer connects a 12C compatible smart sensor to the dedicated auxiliary 12C port of the module. When the SPI (or 12C) is connected to the host MCU, developers can use the auxiliary 12C interface (AUX_CL) of the TDK pipe flow transmission InvenSense ICM-20948 module to connect the external sensor to the AUX_DA and manage it through the special register of the auxiliary device of the LCM-20948.
