Sensors | 6-Axis IMU (U6)
The onboard 6-axis IMU option is the TDK InvenSense ICM-20602. This device is comprised of a 3-axis
accelerometer function and a 3-axis gyroscope function. The device provides an I
2
C operating frequency of
100kHz in standard mode and up to 400kHz in fast mode. The I
2
C address is 1101000b (0x68).

9.2.1.
U6 | 3-Axis Accelerometer
Each axis has a separate proof mass. The accelerometers are factory-calibrated and nominally
independent of supply voltage. The MEMS accelerometer has programmable full-scale ranges of ±2g,
±4g, ±8g and ±16g. A wake-on-motion interrupt, user programmable interrupts, and self-test features
are all available. The accelerometer has a 16-
bit ADC that provides output in 2’s
complement format.
The ADC sample rate is programmable from 3.9Hz to 4kHz.
9.2.2.
U6 | 3-Axis Gyroscope
Each axis has a separate independent vibratory MEMS rate gyroscope. The output of each
gyroscope is amplified, demodulated, and filtered to produce a voltage that is proportional to the
angular rate. The MEMS gyroscope has programmable full-scale ranges of ±250dps, ±500dps, ±1000dps,
and ±2000dps. The gyroscope has a 16-bit ADC word length, and the ADC sample rate is programmable
from 3.9Hz to 8kHz. User-selectable low-pass filters enable a wide variety of cut-off frequencies.
