Just a thought ... the APM/IMU provides i2c capable ports right? Anybody knows if the Lego NXT mindstorms ultrasonic sensor is I2C and if it is can I use it (instead of buying a maxsonar unit) to take advantage of the low altitude hold feature of the ardupirateNG code.

 

Thanks.

  • It certainly does, it's actually a pretty decent sensor as well, it might be a little heavy depending on the size of your quad though.
