Notes
CRITICAL WARNING: No pin diagram image was provided, and the datasheet section supplied contains no pin number table. Pin numbers have been set to "?" for all rows. The pin names and functions listed above are inferred from the device description and typical ICM-20948 functionality, but the actual pin-to-number mapping cannot be determined from the source material provided.
To obtain the correct pinout with accurate pin numbers, consult:
- The official ICM-20948 datasheet section "4.1 PIN OUT DIAGRAM AND SIGNAL DESCRIPTION" with the accompanying pin diagram
- The package drawing for the 24-TFQFN module
Do NOT use this table for PCB layout or design without verifying pin numbers against the official pin diagram.
