9-Axis IMU
Figure 57: OSD3358-SM-RED IMU circuit
Figure 57 shows a 9-Axis IMU U23 powered by SYS_VDD1_3P3V rail and connected to the
processor on the I2C0 interface. This sensor sits on the horizontal axis of the board that cuts the
board in half. The chip is located at coordinates (3485 mil, 1075 mil) from the bottom left of the
board oriented in the same way as shown in Figure 57. It is comprised of a 3-axis gyroscope, a
3-axis accelerometer and a 3-axis magnetometer making the device a 9-axis motion tracking
sensor. Each of the axes have a 16-bit ADC to digitize the sensor outputs.
