Nine axes in one chip: a three-axis gyroscope, a three-axis accelerometer and an AK8963 magnetometer stacked inside the MPU-9250, all read out at 16 bits. The magnetometer is what earns its keep - gyro and accelerometer alone drift in yaw, and a compass gives an absolute heading to correct against, which is why this turns up in flight controllers and self-balancing robots. The board carries a 3.3V regulator so 3-5V on VCC is fine, but the I2C and SPI pins are 3.3V logic.
Key features
- 9 axes: gyro, accelerometer and magnetometer
- Gyro +/-250 to +/-2000 deg/s, accel +/-2 to +/-16 g
- Magnetometer +/-4800 uT at 0.6 uT/LSB
- I2C up to 400 kHz (0x68/0x69) or SPI
- 3 - 5V into the onboard 3.3V regulator
- 3.3V logic - level-shift from a 5V Arduino
