VDD (Pin 1, Pin 15): This is the primary power supply input pin. The voltage required here is typically 3.3V, ensuring the proper operation of the device.
VDD_IO (Pin 2, Pin 16): This pin is used to supply power to the I/O interface s and ensures proper communication between the gyroscope and connected devices.
GND (Pin 3, Pin 17): Ground pin, connected to the system ground to complete the circuit.
GND_IO (Pin 4, Pin 18): Ground pin for the I/O section. It is crucial for proper voltage reference and signal integrity in communication.
SDO (Pin 5, Pin 19): Serial Data Output. This pin provides the data output through SPI communication, where sensor data is transmitted serially.
SCLK (Pin 6, Pin 20): Serial Clock Input. This pin is used to provide the clock signal for SPI communication.
CS (Pin 7, Pin 21): Chip Select. This pin is used to enable or disable the communication with the device in an SPI interface. It is active low.
VDDO (Pin 8, Pin 22): This pin powers the output section, ensuring the gyroscope output data is properly delivered.
INT1 (Pin 9, Pin 23): Interrupt 1. It is used to signal important events or thresholds in the gyroscope data to the system.
INT2 (Pin 10, Pin 24): Interrupt 2. Similar to INT1, but typically for different or additional interrupt conditions.
DRDY (Pin 11): Data Ready. This pin indicates when the gyroscope has new data available, signaling to the microcontroller or processor.
N/C (Pins 12–14): These are no-connect pins that do not have any electrical function in the device.
