# MPU-6050 IMU

The MPU-6050 module is the primary IMU used by the v1 reference. It shares the I2C bus on SDA D6 and SCL D5. Correct physical orientation and correct axis interpretation are prerequisites for stable control.

# Optional VL53L0X

The optional altitude-assist variant supports a VL53L0X range sensor on the same I2C bus. Firmware v1.0.0 expects fresh valid range data before enabling the assisted Takeoff/Landing path.

OPTIONAL

Manual flight does not require the VL53L0X. Keep the first build simpler unless altitude assistance is part of your test goal.
